José Rio 49f96d7f1e fix(overlays,picker): remove invalid aria-hidden attribute (#30563)
Issue number: resolves #30040

---------

## What is the current behavior?
- The usage of `aria-hidden="true"` attributes both on overlay and
picker components was causing some console error/warnings messages.
- This was being caused due the fact of the activeElement (focused
element) was inside those elements with this attribute that's equal to
true in all cases.

## What is the new behavior?
- There is no need of making usage of this attribute due the facts:
- 1. Once overlay is closed the focus will be redirect to the element
that triggers the overlay, this way screen readers will be also
redirected to the same context of focused element.
- 2. After overlay is closed, it will be set as a `display: none;`
through the selector `:host(.overlay-hidden)`, which by itself will
disable overlay content for the screen readers.

- Removed overlay tests since they were basically checking about
`aria-hidden` attribute.
- Updated PickerColumn and PickerColumnOption structure in order to fit
the a11y needs.
- Added a focus management system to better drive users when making
usage of keyboard navigation inside picker.
- Skip A11Y test validation when reported violation is color contrast
related.

### ⚠️ NOTE:
- Reported devTools issue/warning when selecting picker is **from now
on** expected due to focus an input that's set with `tabIndex="-1"` and
`aria-hidden="true"` - Which turns into an A11Y violation when it gets
focused.
It happens that it gets focused dynamically in order to open the native
numeric keyboard **once user selects highlighted picker values zone**,
in order to allow users to insert numeric values through the keyboard.
If this `aria-hidden` and `tabindex` are removed/updated, the existing
functionality will be lost since ScreenReaders will start to ignore the
updated value through the PickerChange and will be focused onto the
focused input.
This mentioned input has an onChange event that's used to update the
`aria-valuetext` on each `picker-column` which is being capture by the
ScreenReader.
That said, this new devTools reported issue/warning is a false positive
since A11Y behaviour is being covered through a different perspective.

## Does this introduce a breaking change?

- [ ] Yes
- [X] No

Testing Local Ionic Framework with ng add

This guide shows you how to test the local Ionic Framework build with a new Angular application using ng add. This is useful for development and testing changes before publishing.

Prerequisites

  • Node.js and npm installed
  • Angular CLI installed globally (npm install -g @angular/cli)

Build Local Ionic Framework

  1. Clone the repository (if not already done):

    git clone https://github.com/ionic-team/ionic-framework.git
    cd ionic-framework
    
  2. Pull the latest from main

    git pull origin main
    
  3. Install dependencies and build the core package:

    cd core
    npm install
    npm run build
    
  4. Install dependencies, sync the core build and build the Angular package:

    cd ../packages/angular
    npm install
    npm run sync
    npm run build
    
  5. Create a tarball:

    cd dist
    npm pack
    
  6. Copy the tarball to Downloads:

    cp ionic-angular-*.tgz ~/Downloads/ionic-angular.tgz
    

Test with New Angular App

  1. Create a new Angular app:

    # Change to whichever directory you want the app in
    cd ~/Documents/
    ng new my-app --style=css --ssr=false --zoneless=false
    cd my-app
    
  2. Install the local @ionic/angular package:

    npm install ~/Downloads/ionic-angular.tgz
    
  3. Run ng add:

    ng add @ionic/angular --skip-confirmation
    
  4. Serve the app:

    ng serve
    

The local Ionic Framework build is now active in the Angular app. Changes to the Ionic source code require rebuilding the packages and reinstalling the tarball to see updates.

Project Structure

common

This is where logic that is shared between lazy loaded and standalone components live. For example, the lazy loaded IonPopover and standalone IonPopover components extend from a base IonPopover implementation that exists in this directory.

Note: This directory exposes internal APIs and is only accessed in the standalone and src submodules. Ionic developers should never import directly from @ionic/angular/common. Instead, they should import from @ionic/angular or @ionic/angular/standalone.

standalone

This is where the standalone component implementations live. It was added as a separate entry point to avoid any lazy loaded logic from accidentally being pulled in to the final build. Having a separate directory allows the lazy loaded implementation to remain accessible from @ionic/angular for backwards compatibility.

Ionic developers can access this by importing from @ionic/angular/standalone.

src

This is where the lazy loaded component implementations live.

Ionic developers can access this by importing from @ionic/angular.
