[[ https://developer.blender.org/D7913 | D7913 ]] broke xrefs/links to other types and permalinks in the docs. This makes the python api docs for 2.90 and 2.91 completely unusable.
[[ https://developer.blender.org/D7913 | D7913 ]] got partially reverted in commit e893430a6306ded059270e7df9d78180cdc0d9e3. That didn't fix those two issues though, so it should be fully reverted.
As you can see here, i'm not able to click `bpy_struct.id_data`, because no <a> tag got generated in the html.
Here you can see a working, but wrong permalink, generated by clicking the little chain. (It should be `bpy.types.MeshVertices`, not `bpy.types.MeshVertices.MeshVertices`)
