Attachment: A test case

Attaching file is a test case where our fast-path apz-aware listener notification doesn't work, but it does work on Chrome.

I created this test case from scratch by inspecting temu's captcha structures (bug 2031963).

Unfortunately I can see the captcha in question via Firefox VPN, but I can't use Firefox VPN because of bug 2052408 so that I am not confident whether fixing this bug would fix bug 2031963.

The nearest scroll container may not have a ViewID (e.g. an in-process
iframe's root scroll container, for which APZ has no APZC).
