Okay this is ready for review, the 3.7 Linux build correctly picks up the GC tests and they pass:

Including plotting tests (ALLOW_PLOTTING=true)
Including garbage collection tests (GC_TEST=true)

Then once pyvista/pyvista#958 is in we can merge!

(The windows 3.6 is just a download timeout error, I don't have permissions to restart it)

I restarted Azure but it seems like Github Actions is still not happy

[GuillaumeFavelier]

BTW @pyvista/developers can we allow @larsoner to restart the CIs?

[larsoner]

Okay finally green, ready for review/merge from my end @tkoyama010 !

This is the longest I've ever seen a PR been open... and still make it to review/merge.

Good idea @akaszynski, done in https://github.com/pyvista/pyvistaqt/issues/270 so I'll merge!
