Component used: androidx.core.view.WindowInsetsAnimationCompat Version used: 1.13.0-beta-01 Devices/Android versions reproduced on: Android 14

• Sample project: (Android's official with no change) - https://github.com/android/platform-samples/tree/main/samples/user-interface/window-insets to which I've added in RootViewDeferringInsetsCallback the following toast to evidentiate the issue:

override fun onStart(
    animation: WindowInsetsAnimationCompat,
    bounds: WindowInsetsAnimationCompat.BoundsCompat,
): WindowInsetsAnimationCompat.BoundsCompat {
    if (animation.typeMask and ime() != 0) {
        Toast.makeText(
            context,
            "keyboard height: ${bounds.upperBound.bottom - bounds.lowerBound.bottom}",
            Toast.LENGTH_LONG
        ).show()
    }

    return super.onStart(animation, bounds)
}

• A screen record showing the issue (if UI related):
  • added a screen recording showing the issue when using gesture navigation - UnexpectedKeyboardHeightToAnimate.mp4
  • added a screen recording showing no issue when using navigation buttons for navigation - RightKeyboardHeightToAnimate.mp4

Issue description:

• Saw it in my own app, reproduces also in the official sample
• If on a phone in landscape, only when using gestures navigation WindowInsetsAnimationCompat#onStart using bounds.upperBound.bottom - bounds.lowerBound.bottom gets us actually the height of the navigation bar when checking for the IME animation bounds.
• If on a phone in landscape, when using navigation buttons for navigation WindowInsetsAnimationCompat#onStart using bounds.upperBound.bottom - bounds.lowerBound.bottom gets us 0 (as expected) if checking for the IME animation bounds.
• This unexpected behavior can lead to UX issues.

Note: I was using the IME animation bounds as a more dependable way to get the keyboard height since as shown in https://issuetracker.google.com/issues/361027506 WindowInsetsAnimationCompat.Callback#onProgress can sometimes unexpectedly use 0 for the keyboard height.
