This PR should also have the following in the PR description and the message of commit d330cd1:

Supersedes and closes #35754

BridgeAR · 2020-11-19T16:20:42Z

@ExE-Boss I added a reference to the issue description but I'd just close the PR manually when this PR lands.

Actual fix LGTM (pending fixed messages changed in tests probably?)

Also - what semverness should this have?

@benjamingr

Also - what semverness should this have?

Probably semver‑patch and be backported to v14.x, given that #33449 wasn’t a semver‑major change either.

Thanks so much for fixing this up. Really nice to surface the null prototype too.

BridgeAR · 2020-12-12T20:54:19Z

@ExE-Boss the failure is an old run and not properly updated :)

Is this likely to be backported to 14.x LTS? It doesn't seem to be included in 14.15.3 @ExE-Boss
