Is this specific to navigation? Or can this be reproduced with another other Composable component?

It only happens inside of a NavHost. So, yes, it seems to be specific to navigation.

This was caused by the fix to BackHandler lifecycle aware. The problem here is that the NavController registers its lifecycle and added an observer to the Activity Lifecycle in composition while the BackHandler registers its observer on the Activity Lifecycle in a DisposbleEffect. This means that the NavController will always get Lifecycle callbacks before the BackHandler, so the components listening the the NavController's lifecycle (like the NavBackStackEntry) will always get their Lifecycle callbacks before the BackHandler as well.
This should be addressed by work coming in 2.7 to integrate the BackHandler into the NavHost.

Integrate BackHandler into NavHost
Instead of NavHost taking over the onBackPressedDispatcher from the
Activity, we should just make it use a BackHandler. This will ensure
that it interacters with the other BackHandlers in Compose correctly.
RelNote: "`NavHost` now correctly intercepts system back calls even
after the Activity has been `STOPPED` and `RESUMED`."

Description
Summary:
Using
Steps to Reproduce:
Use ExifInterface to load a WebP file that does not contain a VP8X header. Call saveAttributes on the ExifInterface object. Attempt to open the resulting WebP file. Expected Result: The WebP file should remain valid and openable after saving attributes.
Actual Result: The WebP file becomes corrupted and cannot be opened properly.
Root Cause Analysis:
If the WebP file does not have a VP8X header, ExifInterface writes a new VP8X header.
When the WebP file's width or height is greater than 8191, the issue arises.
The following code causes the problem:
If the width or height is greater than 8191, left-shifting causes the sign bit to be lost, turning a '1' into a '0', which results in an incorrect width or height.
