Created attachment 431031 [details] screen shot See attached screen shot. On a logged in GitHub issue page, there is a link just above the Subscribe button that says "Notifications Customize". In Firefox and Chrome, the "Notifications" is left-aligned and the "Customize" is right-aligned, all within the one line. In Safari, the "Notifications" and "Customize" run together. Probably a flexbox issue.
Regression is somewhere in this range: https://trac.webkit.org/log/webkit/trunk?mode=follow_copy&rev=278319&stop_rev=278253 My guess is https://trac.webkit.org/changeset/278280/webkit/trunk since it is a <summary> element that is the flex container here.

The problem here is the https://trac.webkit.org/changeset/278280/webkit/trunk change, which makes <summary style="display: list-item;"> fall back to <summary style="display: flex;">.
Should probably just revert bug 190065, it doesn't sound like it is correct.
