Copied from 222259: For additional context, I believe this may occur in STP too. Please compare the behavior of Safari to Firefox on https://codepen.io/comp615/pen/bGqbrEx Click the "right" button a few times. In Firefox (correct), on hitting C, D, E...the scroll is moved so that the selected item aligns with scroll-padding taken into account. In Safari, (Wrong), D does not move the scroller (incorrect because it's behind the scroll-adding)...E also does not (wholly wrong because it's not even in the scroll frame)... and from there it moves the item alternatingly correctly

Looks like this behavior was added purposefully, but it feels like it isn't spec compliant. *** This bug has been marked as a duplicate of bug 42593 ***
