Checking for nested css support (#223497, #249263) via JavaScript using `CSS.supports("selector(&)")` doesn't work. I believe the expected behaviour is that it would return true in browsers that do support it (such as Safari Technology Preview), Chrome Canary does return true for this check.

This looks like a dupe of Bug 252301. What version were you testing?

Sorry, missed that in my search. Tested on latest Safari Technology Preview, version 165. Just tried to run the latest build from https://webkit.org/build-archives/ (for the first time) but can't get it to run. Will check on the new Tech Preview when I assume it drops in the next couple of days.
