Importing plotly express may fail over its fiddling of the globals object

As detailed here on StackOverflow there is an interoperability corner case when using pytest, where importing plotly express may fail over this line of code.

I wonder if other people were able to import plotly express inside pytest managed test code at all.

Yeah, this globals thing was pretty lazy. It should be fairly mechanical to fix if someone wants to open a PR though! Basically we just add the _r-suffixed scale after each scale.

That said, yes, we use pytest to test Plotly Express, both locally and in CI.

OK so #3713 should resolve whatever issue you're hitting that I'm not. Even if I can't replicate it, it's good to get rid of this kind of code smell :)

Thank you so much for solving this, pytest interoperability is straight now.
