pip-pre will fail until matplotlib/matplotlib#30575 is addressed, so in this goes. Thanks @sappelhoff !

Owee, I'm MrMeeseeks, Look at me.

There seem to be a conflict, please backport manually. Here are approximate instructions:

1. Checkout backport branch and update it.

git checkout maint/1.10
git pull

2. Cherry pick the first parent branch of the this PR on top of the older branch:

git cherry-pick -x -m1 ae1d4ae9686c91a195b7f83b57fdc60124b219aa

3. You will likely have some merge/cherry-pick conflict here, fix them and commit:

git commit -am 'Backport PR #13423: TYPO: add missing version prefix'

4. Push to a named branch:

git push YOURFORK maint/1.10:auto-backport-of-pr-13423-on-maint/1.10

5. Create a PR against branch maint/1.10, I would have named this PR:

"Backport PR #13423 on branch maint/1.10 (TYPO: add missing version prefix)"

And apply the correct labels and milestones.

Congratulations — you did some good work! Hopefully your backport PR will be tested by the continuous integration and merged soon!

Remember to remove the Still Needs Manual Backport label once the PR gets merged.

If these instructions are inaccurate, feel free to suggest an improvement.
