Sphinx class inheritance diagrams not linking classes correctly

[hamogu]

E.g. at https://astropy.readthedocs.io/en/latest/visualization/index.html#module-astropy.visualization

click on any class in the graph-viz Diagram - None of them work, because there is a "/latest/" missing in the url. I'm reporting this here, but I'm not entirely sure if this is a sphinx-automodapi issue or related to some configuration in astropy itself.

The diagram links point to a different .rst than the class name links.

I've run into the broken links again, today.

It's useful to link to these following issues as PRs and most of the relevant discussions happened on them:

astropy/astropy#4935

and upstream fixes and more discussions on how it should be fixed instead here, in this extension:
sphinx-doc/sphinx#2484
sphinx-doc/sphinx#6454

This is actually a bug in Sphinx after all. See sphinx-doc/sphinx#10576

Thanks for investigating and opening upstream fix!

I think this is fixed by #172
