When swiping on posts, sometimes I go to a bit too far and then I move it back (without letting go of the swipe). In these cases it always registers it as the furthest option I swiped to, not the one I’m actually selecting at the end.
For example, if I intend to swipe to an upvote but go slightly past to bookmark, then I go back in the previous direction to upvote still without releasing the swipe, it will register the bookmark option
I was able to replicate this undesirable behavior
Edit: it seems if you hover over your final selection until you feel haptic feedback it works as intended but if done quickly you get the behavior described in the post
