Add missing early-exit in collectMatchingRulesForListSlow for @scope rules
https://bugs.webkit.org/show_bug.cgi?id=311339
Reviewed by Anne van Kesteren.
In StyleInvalidation mode, we only need to know whether any rule matches.
The isFirstMatchModeAndHasMatchedAnyRules() check enables this early-exit,
but the @scope code path with multiple scoping roots was missing it —
the `continue` bypassed the check, causing unnecessary rule processing.
