Not sure if I see a bug in the video. The cursor changes to vertical line for text selection, and snaps to closest text line, which seems expected.

no other line under the text, and i am not making any selection, just move cursor, cursor should not go there. And if i stop move after cursor vertical jump, and make a click, the cursor will vertical jump back to the text. Or double click, it will selectect the text before jump.

If there is, cursor should not goes ther by itself either, because i am moving horizontally, i don`t expect it jump vertically, and why this will not happen on ipad os 15?
