android: keyboard/text editor focus issue

[ItsKaa]

Describe the bug

On Android/Mobile, the main text editor ('Send a message...' box) seems to remain the focused area when opening dialog boxes such as sticker/emoji/gif or pages such as settings, you have to first manually close the keyboard and then focus something else like the timeline (which isn't always easy in a full timeline either) in order to correct the issue. This is particularly annoying when chatting and wanting to include an emoji/sticker.

Note that in this video you can't see my taps, I did first try to tap on the sticker/emoji search and room name text boxes but it does not work.

Reproduction

1. Open a room
2. Tap the "Send a message" text editor and optionally write some text
3. Tap on the emoji/stickers/gif button
4. Try typing to search: does not get registered to the emoji/sticker/gif search
5. Try to tap on the search box: focus does not shift

Expected behavior

When opening dialogue boxes, the text editor should automatically unfocus from the main chat box.
Ideally for sticker/emoji/gif, if the keyboard was already open it should automatically focus on the "Search" box so that typing will immediately cause it to search, afterward the focus should shift back to the main text editor.

Platform and versions

1. OS: Android 17
2. Sable version: v1.21.0 (7675aa1)
3. Matrix homeserver: selfhosted with Synapse

Issue verified on three different devices with two different homeservers.

Additional context

Similar to #1952, this issue has been fixed in the Nightly build, it does require tapping on the search box even when the keyboard was open. and after inserting an emoji you have to manually tap on the text editor again, but I'd consider it resolved.

---

However, one somewhat related bug I did notice:
Insert an emoji using the emoji button from Sable (not the emoji button from your keyboard), when you try to remove that emoji the keyboard will close, even with multi-select. What does work is if you select the emoji and then replace it with text rather than using backspace.

Happening on both Stable and latest Nightly. Not sure if it's focus related or something else but for now I'll leave this case open.
