Fixes #5949

Dispatches an InputEvent before the change event when keyboard-navigating radio buttons with arrow keys, matching native <input type='radio'> behavior where both input and change events fire on user interaction.

Changes

  • Modified SingleSelectionController.handleKeyDown in radio/internal/single-selection-controller.ts to dispatch an InputEvent before the change event
  • Added test in radio/radio_test.ts to verify input event is dispatched on keyboard navigation

Testing

Added a new test case dispatched an input event on user navigation that verifies the input event is fired when using arrow keys to navigate radio buttons.
