Can anyone affected by this share their eslint config, and also more of the stack trace?

I think I found something. Might open a PR soon

[ljharb]

@taddei I have a fix already, I just need a regression test.

[taddei]

ok cool, np.
feel free to discard this: #1786

[taddei]

the hotfix is just a patch though. I noticed that it's trying to see if the method constructor is deprecated, should probably skip core class methods like this one?

[ljharb]

aha, thanks, that did it :-)

[bdwain]

thanks for fixing this so quickly!
