event-timing/idlharness.any.html targetSelector subtest shouldn't be included in interop 2025

Test List

event-timing/idlharness.any.html - attribute targetSelector subtest

Rationale

The targetSelector attribute was added to Event Timing API on October 17, 2025, which is way after the interop's scope, but currently it looks like it's a part of interop 2025. Considering that it's a very recent addition to the spec, it shouldn't be included for this year.

I don't know if it's possible to exclude a single subtest though because we want others to be included.

Hey @mmocny and @smfr, could you please review this?

I agree this shouldn't be part of interop, but also don't know what the best way to selectively remove just this part of test.
