1625813 - Fixed element inside sticky element clipped incorrectly during scrolling on this page

Status: RESOLVED WONTFIX

(Core :: Web Painting, defect, P2)

Description

[Markus Stange [:mstange]]

When scrolling up on https://www.aa.com.tr/en/europe/italy-101-year-old-influenza-survivor-beats-covid-19/1783890 , the fixed blue bar gets intermittently clipped by a scrolled clip.

It looks like the fixed bar is a position:fixed element that's located inside of a position:sticky element.

Possible duplicate of bug 1514291.

FYI,
layers.async-pan-zoom.enabled=false fixes the issue on Nightly76.0a1 Windows10.

I can reproduce, but only with WR disabled. With WR enabled it works fine (tested on macOS). This does seem similar to bug 1514291, marking as dep for now.

Confirmed that this is fixed by WR (WONTFIX for non-WR which is going away).
