These tests don't chdir back to the original directory on exit, so anything using the current directory would be in the temporary directory of this test. Most notably, any image comparison results would be dumped in that temporary directory instead of the usual `result_images` in the current directory.

PR summary
These tests don't chdir back to the original directory on exit, so anything using the current directory would be in the temporary directory of this test.
Most notably, any image comparison results would be dumped in that temporary directory instead of the usual
result_imagesin the current directory.I noticed this while debugging #27723, as the failing test images were not in the artifacts, and logs showed them saved in a temporary directory: https://github.com/matplotlib/matplotlib/actions/runs/8458560380/job/23173084420#step:13:183
