Thanks. I thought there weren't more uses of ftype and ziptype (should have checked).

I guess the _broadcast_type can be removed replacing its uses by _promote_op + typestuple, given it is short enough.

Also, could you add a test so this does not go undetected again?

Oh, it made the tests fail. I guess each PRs last test ran before the other one was merged, that's why it went undetected. (Yes, our current master fails tests.)

I see. I wish there was a mechanism to avoid this kind of issue.

https://github.com/servo/homu But IIRC it doesn't support AV which we need.

I'll merge this even though it hasn't been open for long to avoid test failures the whole day. If this needs adjustments, it is better to do from a state where master is not failing.

Bisection suggests that the first problematic commit is 02596f9

For context to above. I previously had this comment here, but moved it to #19421

Thanks @martinholters! This change was a planned touchup to #19518, so LGTM.
