4.0.0: sphinx warnings `reference target not found`

[kloczek]

On building my packages I'm using sphinx-build command with -n switch which shows warmings about missing references. These are not critical issues.
Here is the output with warnings:

Can you confirm if this was an issue with previous versions?

[kloczek]

It was et least in last 3-4 months (I had no time to report that .. sorry)

[stephenfin]

No problem. I haven't seen this issue personally (and I built all my documentation with the -W flag so I'd have noticed). If possible, could you find the specific version that this broke on? That'll give me something to work with as I try to investigate this. Alternatively, could you give me a minimal reproducer?

[stephenfin]

Oh, wait, you're referring to the docs for this project. Apologies. I'll take a look now

[kloczek]

Tested and it still needs one small patch

With that patch is possible now generate documentation out of source tree and without tox (which is shorter 😄 )
