Dropping iOS 15 & other old browsers in July 2025

Announcements
25

I am on Android 9 Kiwi Browser 132, using Chrome 132.0.6961.0, but that colour feature is still shown as not supported and I have that warning banner.

See my Feature detection result in WebDev console:

{
	"relativeColor": false,
	"subgrid": true,
	"lookbehindRegex": true
}

@david, maybe rename this topic as it’s not limited to some iOS version, but rather to some browser versions on any OS.

But sorry I have no title idea.

Does current Firefox ESR (older versions) pass the test?
