## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->
Developers have requested that Ionic Framework support the dynamic type
feature on iOS for accessibility purposes. Ionic applications do not
respond to font scaling on iOS which can create inaccessible
applications particularly for users with low vision. Ionic apps on
Android devices currently support the Android equivalent due to
functionality in the Chromium webview.
Developers have also requested a way of adjusting the fonts in their
Ionic UI components consistently.
## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->
- Ionic components now use `rem` instead of `px` where appropriate. This
means devs can change the font size on `html` and the text in supported
Ionic components will scale up/down appropriately
- Add support for Dynamic Type on iOS (the iOS version of Dynamic Font
Scaling)

## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->
The back button on iOS uses the same background and foreground colors on
hover + focus making it impossible to read
## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->
- Back button uses a transparent background color on hover + focus to
match the behavior of `ion-button`

## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->
The `navigation` test for `ion-back-button` errors out in the console
and doesn't display when attempting to host it locally.
## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->
Test removed, since it had no E2E file and the functionality appears to
be redundant with the tests for `ion-nav`.

This is the first PR to introduce the infrastructure required to add
test generators to the Ionic Framework project. This PR introduces the
file name changes necessary to support two playwright configs, so I
recommend reviewing the PR by commit:
1e5012cea1
- Created a `playwright.config-legacy.ts` file and updates
`package.json`.
- Running `npm run test.e2e` will run the generator tests, and running
`npm run test.e2e.legacy` will run the legacy tests.

- Updates the GitHub Action scripts to run both the modern and legacy
E2E tests. I added command modifiers to avoid collisions with output
directories.

- Updates `*.e2e.ts` files to have the legacy format name:
`*.e2e-legacy.ts`. This naming scheme is required for the two Playwright
configs to pull in the correct files. When migrating tests to
generators, team members will rename the file to remove the `-legacy`
part.

(warning: lots of files!)
- Updates the `*.e2e.ts-snapshots` directories to have the legacy format
name: `*.e2e-legacy.ts-snapshots`. The screenshot directory in
Playwright is generated based on the test file name which is why we are
updating the screenshot directory. When migrating tests to generators,
team members will rename the directory to remove the `-legacy` part.

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;
```
