We have NodeImplVtbl for such cases, you could add another entry there.

We have quite a few tests for that. I'd expect your patch to break them (and,
in any case, extending tests will give us answer how it's supposed to work).

Looking at the example, it seems like innerText should somehow propagate the
exception.
