After switching accounts, using the Android system back button/gesture doesn't close media on any page other than the main timeline. The input instead falls through to the page the media is on, such as closing a profile page, even while the media stays open. The only way to fix the issue is to fully restart the app.
This issue does not happen on the main page, the media properly closes. It does not happen if you have not switched accounts, and I have not found any other causes. It always closes properly in the official Bluesky app.

idk if it will work due to it being android-specific, i tried doing a fix on https://tangled.org/kris.kralsei.stream/tenna.party/commit/b1322f1d3526a9b916a3f2e9ed14f8617a431cfe
