Only writing here because it seems to be GrapheneOS related, not app specifically, and I'm not award of other community dealing with this software.

I currently have OpenBoard with two languages installed- English and my native. My issue happens no matter if I have open board or GrapheneOS stock keyboard setup.

When I'm trying to erase the first two letters of a word I'm currently working on, it will then highlight the whole word + the space before it. Any change I will make from now on, will delete that space and will merge these two words together. It only happens if I already finished working on this word and I'm going back to fix this.

Video attached below to maybe better explain the issue. Any help greatly appreciated
