Description

Steps to reproduce:

  1. Go to https://perfht.ml/2CpYC2S
  2. Scroll down in the header to the very bottom.
  3. Hover the memory track for Web Content (2/2) in the right half of the track, where the orange graph is very low.
  4. Without moving the mouse, scroll down.
  5. Unhover.

Expected results: At step 4 you shouldn't be able to scroll down more. So that step 5 doesn't make the header jerk.
