It's not possible to swipe the screen to the right to go back to the previous page if you swipe over a comment that you have privileges to remove (i.e. swiping left). I assume these comments also consume the swipe right actions.

If you plan on having other actions for right swiping on comments, it would be nice if swiping to go back would still work if you start the swipe at the left edge of the screen (start at edge -> go back, start further in -> swipe-right action on comment).
