Thanks for reporting!
I tried to repro on a Galaxy Tab S9FE (Android 14) with today's Nightly, and for me it worked as expected. There's differences between a phone and a tablet of course, so I don't know if I just might not encounter the issue (different aspect ratio, larger screen, ...). Could you try with today's Nightly again to confirm that some very-recent changes in that area did not fix this issue?
