## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->
In Angular when the segment buttons are dynamically rendered, the
segment will not set the active visual state for the selected segment
after the re-render.
## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->
- In Angular the segment will set the active item visually when the
items are dynamically changed
Previously this PR:
https://github.com/ionic-team/ionic-framework/pull/28837 aimed to
resolve https://github.com/ionic-team/ionic-framework/issues/28816. I
have confirmed that the modified approach in the dev-build fixes#29414
and #28816 and the previous change is no longer needed.

## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->
The documentation around `ionChange` not being emitted when
programmatically changing the property associated to the "value" is
either inconsistent or missing from certain components.
## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->
- Adds the documentation to the missing components.
- Makes the documentation consistent across components.

## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->
The value is set on Segment asynchronously when binding it in Angular.
However, the timing works out such that the value changes after
`connectedCallback` is fired but before any Stencil Watchers are
configured. As a result, our `value` property watcher does not fire
which causes `ionSelect` to not be emitted. Segment Buttons rely on this
event to know when to update their state (if the value changes such that
a segment button is now selected). This results in a checked segment
button not appearing checked.
This is similar to other issues that have been fixed:
https://github.com/ionic-team/ionic-framework/pull/28510https://github.com/ionic-team/ionic-framework/pull/28488https://github.com/ionic-team/ionic-framework/pull/28526
## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->
- Segment now emits `ionSelect` on `componentDidLoad` so that any
descendant segment buttons can update correctly.

This is a timing issue with Stencil, so I am unable to write a reliable
automated test. Reviewers should test the dev build in the repro
provided in the linked issue.

The fix in
1167a9325f
uncovered a WebKit bug where scrolling an element using `scrollIntoView`
during an accelerated transition causes the segment to jump during the
transition. `scrollIntoView` can cause parent elements to also scroll,
and given that the entering view begins outside the viewport, it's
possible this triggered some sort of WebKit bug where it was trying to
scroll the element into view.
## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->
- Updated the internal implementation to use `scrollBy` instead of
`scrollIntoView`. `scrollBy` does not attempt to scroll parent elements
which avoids the WebKit issue.
- I also updated the initial scroll to be instant rather than smoothly
scroll. If a segment is added to the DOM, I'd expect it to be added with
the correct scroll position (after the first render that is), so
animating on load seemed like a strange behavior. User interaction will
continue to use smooth scrolling though.

## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->
When a segment button is clicked, the segment will auto-scroll to
position the newly active button fully in view. However, this behavior
does not occur on first load. This means that when a segment is
initialized with a `value` corresponding to an off-screen button, the
button will remain off-screen.
## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->
The same auto-scroll behavior from button click now also occurs on
component load.

## What is the current behavior?
The value property of the segment component in Ionic Framework currently
only accepts string values.
## What is the new behavior?
This pull request updates the "value" property of the segment component
to accept a union of string and number types. This allows for more
versatile data input in the segment component, particularly for users
who work with numerical data.

The Ionic Framework team would like to re-evaluate our approach to improving customization options when building mobile applications. We are looking at other solutions that a) make customizing an app UI easier and b) are applicable to a broader set of developers.
Before users had to know the exact opacity that the MD/iOS spec called for in order to change the hover or focused background color. This allows them to change the background without having to know the opacity.
- changes apply to Action Sheet (Buttons), Back Button, Button, FAB Button, Item, Menu Button, Segment Button, Tab Button
- greatly reduces the requirement by users to set the background hover, focused states for dark modes and custom themes, also eliminates the need to know what the hover opacity is for each based on the spec
- updates the MD dark theme per their spec
- adds a component guide for internal use changing Ionic components

BREAKING CHANGE:
*Activated Class*
The `activated` class that is automatically added to buttons on press has been renamed to `ion-activated`. This will be more consistent with our `ion-focused` class we add and also will reduce conflicts with user's CSS.
*CSS Variables*
The `--background-hover`, `--background-focused` and `--background-activated` CSS variables on components that render native buttons will now have an opacity automatically set. If you are setting any of these like the following:
```
--background-hover: rgba(44, 44, 44, 0.08);
```
You will likely not see a hover state anymore. It should be updated to only set the desired color:
```
--background-hover: rgba(44, 44, 44);
```
If the opacity desired is something other than what the spec asks for, use:
```
--background-hover: rgba(44, 44, 44);
--background-hover-opacity: 1;
```
