Not GP, but he's absolutely right, it's been pissing me off for years now. Only thing I can remember off the top of my head is nested selectors still not highlighting properly. They partially fixed this a few months ago but that's it. I guess we're all waiting on GHCP to prioritize and fix it now?

Not OP but I remember working on a team that just put up with nonhighlighted nonintelligent CSS because it was embedded in a handlebars template. Of course there is an extension that's supposed to fix this but it was flaky and broke often. An easy fix was to move CSS to a separate file for import but that was a big change for these guys.
