clarkwinkelmann TeamF it should still work. If you have external images in a post, this can cause Flarum to jump to the wrong place because it calculates the jump before the image are actually loaded, and cannot guess their height in advance.
clarkwinkelmann TeamF unfortunately none of the currently available upload extensions seem to take care of pre-setting the height of images either. That's something those extensions could do though since they parse the image at some point and could retrieve the size.
