Device: Samsung Galaxy Tab S10 Ultra
OS: One UI 8 (Android 16)

Steps to reproduce:
1. Disable "Full screen in split view" in Settings > Advanced features > Labs > Multi window
2. Open Adobe Acrobat Reader in split screen with any other app
3. The status bar remains visible at the top (expected behaviour)
4. Adobe Reader renders at full screen height instead of resizing below the status bar, causing the notification bar to overlap the app content

Expected behaviour: The app should respect the available window area and resize its layout below the status bar, as other apps do in this configuration.

This appears to be a window insets handling issue where the app does not account for the status bar when running in a non-fullscreen split view window. Other apps on the same device resize correctly.
