Hi Team,

While going through Blink's commit, I came across another failing testcase:

Test Case - https://jsfiddle.net/t7qd4brz/

^ WebKit ToT is matching Firefox Nightly 115 in this test case, while Chrome Canary 115 is showing text as expected.

Blink Commit - https://chromium.googlesource.com/chromium/src/+/c397af87189cc4ea1370ec0afbc1d80cc5c4a56f

This patch refers to following WPT: https://wpt.fyi/results/css/selectors/is-where-parsing.html?label=master&label=experimental&aligned&q=is-where-parsing

From above, we only fail single test case:

> Nested inside :host, with combinators	

______

Just wanted to raise to get this fixed.

Thanks!

Chrome Canary 120 now matches with Safari Technology Preview 180 and Firefox Nightly 120 and don't have any 'green' text.

Marking this as 'RESOLVED INVALID'.
