When I reply in a topic (with several answers so the screen has to scroll) on desktop the screen goes to where my message is (at the bottom). However, when I try the same in mobile, it just goes to a random place in the middle of the topic and I have to manually scroll down to get to my message.

This happens here on the official testing version so is this some kind of bug or am I'm missing something?

It just isn't good usability as the user is suddenly "lost" in the middle of the post.
