Related to - #1840 and #1683, but for mobile browsers.
It seems that currently in mobile browsers (the same on desktop in mobile view) rules with :has() use ExtendedCSS instead of native :has().
Steps to reproduce
- Add this rule:
- Go to - https://example.org/
- Open devtools and search for
div
In desktop view native :has() is used.

In mobile view ExtendedCSS is used.

The same occurs on real Android device.
