Description

This pull request fixes internal references to plugin names which changed to be the human-friendly name in #2680 (not yet released), but missed updating a few cases, resulting in moment maps not being linked correctly.

I confirmed locally that this test fails on main without this patch as follows:

E       AssertionError: assert ('Pixel Axis 0 [z]' == 'Pixel Axis 0 [z]'
E
E           Pixel Axis 0 [z] and 'Pixel Axis 0 [y]' == 'Pixel Axis 1 [x]'
E
E         - Pixel Axis 1 [x]
E         ?            ^  ^
E         + Pixel Axis 0 [y]
E         ?            ^  ^)

Wow, the fix is very subtle. Thanks for hunting it down. I added a check as regression test. I think this is good to merge once CI is green. No need for second review.

Thanks for tracking down the offending PR and adding the test! 🎉
