Editing comments doesn't work correctly

When I attempt to edit a comment that I already submitted, especially if I'm trying to backspace text, I put the text cursor at the desired part of my comment but if I backspace more than once (i.e. holding the backspace button), the cursor jumps to the very end and starts deleting the end of the comment.

Interestingly this very same glitch would happen to me on the reddit app when I used to use reddit.

Does anyone else get this on Voyager? Is it a known bug?

Edit: I suppose it would be helpful to add, I'm on Android.
