While testing a preferences fragment built with PreferenceFragmentCompat, I've noticed that the appearance of the preference list is messed up, seemingly at random, whenever an edit text dialog is displayed. If I rotate the screen (using default behavior for config changes with this activity) or switch from another fragment then back to this one, the correct appearance is restored. I manage a change listener in onResume/onPause, but removing that doesn't change anything, so I know that's not related.
I have tried the takisoft fix library as well, assuming that's still relevant. While it might fix other issues, it does nothing for this one.
Any ideas? I've looked for a fix, using every search term I can think of, but finding nothing.
Edit: One MRE, coming right up...

androidx.appcompat - 1.7.1 com.google.android.material - 1.13.0 androidx.preference - 1.2.1(Didn't intend for that list to be in a code block, but the editor wouldn't take it otherwise.)
I did notice something interesting when I was trying to replicate the issue, in that initially I was having trouble with the action bar covering the preference category name. At the time, appcompat was at 1.6.1 and material was at 1.10.0. When I updated either of them to what Android Studio suggested was current (see above), the action bar issue went away, but the preference layout bug started.
When I tried the Takisoft library, it was 1.1.0.
