Problem
As a user I expect the popup to always appear close to the "revision bar".
Steps to reproduce
- Go to a page showing revisions (e.g. https://www.mediawiki.org/w/index.php?diff=2446749&oldid=2428873&title=Extension%3AFlow&type=revision)
- Place the mouse pointer on the "yellow revision pointer" (e.g. ball)
- Click and hold the mouse button
- Move the mouse pointer horizontally towards the right until it is close to the edge of the screen / window.
Expected
The popup consistently shows close (and below) to the revision "bar".
Actual output
Sometimes the pop up shows up on the left side of the page.
Note: This is likely due to the popup tool attempting to be too smart. Whenever there isn't space on the right hand side to fully display the popup it puts it on the left hand side, instead of adjusting the arrow and keeping the "box" in the right place.
