Lilla no, it happen everytime, I mean when the user skip video, it will be still there all the time and when you try to click something under it, will be not clickable.
also I think the problem is related to rtl sites, and is happens clearly direclty on mobile sites, but hard to recreat it from browser developer inspect
just open anypage that have ads enabled
wait for the video ad to show (or when its about to show)
skip it thought the skip button, not thought the X
and it will disapear but anything under it will be not clickable
