If I have a long page that requires scrolling, every 5 or 10 seconds Safari will jump to the top. I have a 2018 MacBook Pro that is 100% updated as of the time of this posting.
I can see something similar happening in Firefox, the page doesn't jump, but the scroll bar will appear every 5 or 10 seconds. Almost like it's trying to do the same thing.
The past 2 semesters I used Safari with no issue. I can workaround it by switching to Firefox, but I would prefer to just keep everything in the same place. Is there a bug that's being worked on?
