Keyboard not appearing in 1-person room on fdroid element app

### Steps to reproduce

Love matrix and love element, great job.

I have a very weird recurring issue on the fdroid version of element (1.6.6) on lineage os . I have a room with only me in it ("Me I and Myself"). On the element client in linux, I can write and drag and drop files into this room, no problem, see this screenshot:

However since some time on android the keyboard does not appear in the room.
I have cleared cache, and I've logged out and in again, and still keyboard does not appear.
It appears normally for all other rooms.


Interestingly, if I press the "share" button on android, I can add files to this room from element.

Amazingly, despite a cache reset and a log out/in, element believes there is some edited but unsent text in this room:


I'm happy to help debug, or to have a hint to reset this room.

### Outcome

I expect the keyboard to appear when I got into a room where I'm allowed to write
