It's actually returning the ticklabel bboxes, not including the
tickmarks themselves.

This PR is affected by a re-writing of our history to remove a large number of accidentally committed files see discourse for details.

To recover this PR it will need be rebased onto the new default branch (main). There are several ways to accomplish this, but we recommend (assuming that you call the matplotlib/matplotlib remote "upstream"

git remote update
git checkout main
git merge --ff-only upstream/main
git checkout YOUR_BRANCH
git rebase --onto=main upstream/old_master
# git rebase -i main # if you prefer
git push --force-with-lease   # assuming you are tracking your branch

If you do not feel comfortable doing this or need any help please reach out to any of the Matplotlib developers. We can either help you with the process or do it for you.

Thank you for your contributions to Matplotlib and sorry for the inconvenience.

Apparently, these need tests, because there are some obvious typos.

[anntzer]

The tests were correctly catching the typos, AFAICT. Fixing them now.

Apparently, these need tests, because there are some obvious typos.

Maybe the failing tests caused some additional paths to be missed, dropping coverage. Ironically, it appears now that the one that was correctly changed is the one with no coverage, and the ones that were missed are covered.
