This test tests unspecified behaviour as far as I can tell. We should probably pass it at some point but doing it correctly likely needs some investigation.

These error results appear because we don't implement step 1 of https://w3c.github.io/user-timing/#convert-a-mark-to-a-timestamp. We didn't implement it before either, but returned a nonsense value instead of throwing.

This reverts commit 1550163.

I verified this. It is stable now. We can remove this.
Is it fine, if I remove this TODO?

If there are tests that pass as a result of that change, sure.
