I believe the test you mention is the only example of this. I kept it
there because I wasn't sure and explicitly requested feedback on it. I'm
happy to remove that test. All the other tests are reported running on
at least one browser.

So, those tests don't pretend to be complete in any shape or form. They
have the advantage that they exist, unlike the more exhaustive tests
that don't exist so far. So, I'm reluctant to drop them on the floor
until we have a replacement for them. You're correct that we shouldn't
spend a lot of cycles on them and should look into replacing them in the
long run, but those have the advantage that they test old part of html
where we are less likely to receive test contributions.
