In bug 1692708 we are going to change ScrollToCSSPixels to a relative operation if there's any on-going animation in APZ triggered by user. In this bug we are going to apply it in the case of no animation as well.

Do you know if this additional change is needed for the Slack case, or is bug 1692708 is sufficient for that?

I think bug 1692708 is sufficient in most cases including Slack basically. This is literally for a race condition where APZ just starts an async scrolling but the corresponding RepaintRequest hasn't yet reached to the content's main-thread, at that moment if JS on the main-thread calls scrollTop, our relative scroll machinery won't be triggered. This bug is for the race case.
So, I am thinking that we can defer this until someone reports to us there's a wobbly scrolling site in the wild.
