What is the problem?
When using the IPInfo popup on the history of an article can cause the dotted lines which mark selected revisions to jump (see screenshot).
I have only reproduced this on Firefox (not Chrome, Edge or Safari).
Steps to reproduce problem
- Login and go to https://thegoodplace.wmcloud.org/index.php?title=Test2&action=history
- Click the first IPInfo "i" popup
Environment
Browser: Firefox 78 and 83.
