Could you elaborate on this expectation update?

I think your argument of "no visual change" of this test
is too weak to support this diff, since almost nothing is
rendered from the beginning.

And certainly the behavior has changed as id attribute
is gone and a new ul is created. You probably need to
explain either (a) this is not a regression but a progression,
or (b) this change is harmless and won't affect real web pages
in a bad way.

At least I would like to understand how this behavior change
happened.
