There was a problem hiding this comment.
It's kind of funny that this placates flake8 but I guess the point is that it cannot know all the places where a global could be introduced. I think it's a reasonable compromise.
Given that the global declaration is not actually needed, I'd make the comment more explicit: "...; declaration placates pyflakes" (something like that) (otherwise someone could just remove it at some point thinking it's redundant)

Fixes #10502
PR Summary
Declare show and FigureManager as global variables because they are created by an _@Backend.export decorator at the bottom or each file. The global declaration and associated comment helps both humans and linters make sense of this non-intuitive situation.
