As reported in the mailing list thread: "missing ticks on inverted log axes"
This should fix a bug introduced by 255f213 that made some ticks disappear on inverted axes.
Fix missing ticks on inverted log axis
Update a test to check inverted log axes
Looks good. 👍
On an mildly related note, would you be willing to re-create all of the svg and pdf in the repository in a separate PR? I think things have changed which, because they didn't make a test fail, are still out of date (file URL etc.).
Thanks for fixing this mdboom. I gave myself a good slap when I saw the problem.
No worries! Glad to have the contribution!
