We also had this issue with the RevisionSlider help dialogue, but it is fixed there now.
Issue
When clicking through the steps of the help dialogue the top edge of the dialogue moves up and down the screen and thus the location of the buttons that the user is trying to click on also moves.
Solution
The top of the dialogue should be fixed at a certain height (as is done in RevisionSlider)

It looks like the relevant stuff for RevisionSlider was T145526 and https://gerrit.wikimedia.org/r/#/c/310329/
Sounds good. To get it right: This would mean that you can keep your mouse in place when clicking through?
We should check if a static position still works with different screen heights. (Just in case we have a fixed top/left absolute positioning)
