Scroll-to-bottom is broken in rooms with things in the headers (AuxPanel)

[anoadragon453]

Description

Riot can still get into a state where its scrollTop value becomes non-int.

This creates problems such as entering a room not scrolling to the correct position, and scrolling to the bottom of a room does not remove the scroll-to-bottom button. A fix was attempted in matrix-org/matrix-react-sdk#2846 but does not seem to have completely solved the issue.

Steps to reproduce

• Happens at some random point. Refresh fixes the issue
• The issue also just seems to be fixed at random points as well, possibly due to functionality introduced in the above mentioned PR

Actually this seems to only happen in rooms with the simple counters Labs feature.

This also seems to happen with rooms with widgets.

You got the values posted in the screenshot above while being entirely scrolled down in a room?

@bwindels That is correct.

Should be fixed on /develop now
