test_transparent_markers[pdf] is broken on v3.3.x Travis macOS #18551
Description
Bug report
Bug summary
Starting with #18545 and the subsequent merge, test_transparent_markers[pdf] has been failing on v3.3.x for Travis macOS. It does not appear to be failing on other systems or other branches. There were no other builds on that branch for 5 days before that, so it may or may not be related to that PR specifically.
I could not reproduce on the Mac Mini either, so I'm not sure how to fix it.
