Other browsers tested:
  Add OK or FAIL, along with the version, after other browsers where you
have tested this issue:
     Safari: -
    Firefox: Never had this problem
         IE: IE11 never had this problem

What steps will reproduce the problem?
(1) Open URL (read the note aside the URL) with at least 1280px window with such that you see a sidebar appear on the right
(2) Scroll down until the sidebar becomes sticky (fixed position)
(3) Mouse over any link within the sidebar
(4) Problem occurs not always. Repreoduce (1) to (3) for 2-4 times to see the issue, it depends probably on the scroll position

What is the expected result?
Sidebar stays at the same place, link renders in :hover CSS styles

What happens instead?
Sidebar jumps 1px down and after about 100ms up again while, link renders normally. When the mouse leaves the sidebar area, sidebar jumps the same way again.

Please provide any additional information below. Attach a screenshot if
possible.
If needed I can try to record it on video, because it is hard to see only with two screenshots. But even if it is only 1px moving around, it is rather annoying because it happens so quickly.
