Steps to reproduce

1. Launch Firefox;
2. Access this link, or any other from a Facebook post notification;

• the (blue) focus-ring fades out after 1-2 second(s);

Actual result

• the (blue) focus-ring persist in page;

Regression range

• First bad: 2019-05-08;
• Last good: 2019-05-07;
• Pushlog: URL;

Additional notes

• S4 set since it has no real impact;
• attached sceenshot to illustrate the persisting issue

For what it's worth, the blue rings fade out for me on Windows 10 (light theme).

It works fine with/without WebRender on Linux. If it's specific for Mac, it's likely an issue in gfx code. I don't see any suspicious changes in the regression range though.

Is this issue happening with/without WebRender?

Happens with gfx.webrender.all on both true/false.
Something that I just noticed, as an additional behaviour on macOS 11:

• opening the link directly, the posts on the "first page" are all highlighted, scrolling down towards the "next page" that wasn't loaded shows posts as expected (meaning that the first 2-3 posts are having the reported issue).

Thank you Cristian. Still weird why this issue happens only on Mac. Setting P3.
