Could you please run the tests (locally this will require either some fairly recent node version or a d8 executable) and fix the current failures?

I assume all this features are already available in V8 at least behind a flag, otherwise that will be another reason why these tests can fail.

It is not enough to add it to the ObjectGroup. It will also need to be added to the ILType (around line 1072).
This may seem like an unnecessary duplication (and I think it is) but that's how it works right now. :)

Good catch, thanks 👍

Will do - I did test this locally but only with a normal fuzzilli release build, hence why I missed the assertion.
