Wrong URL for external package cross-reference

[jaywonchung]

Describe the bug
A cross reference to torch.utils.data.DataLoader is rendered with incorrect links.

Here, torch points to https://pytorch.org/docs/1.10.1/data.html#module-torch.utils.data. data and DataLoader point to correct URLs.

I opened up the objects.inv file provided by PyTorch with Inventory.parse_sphinx and found that it does not have entries for torch and torch.utils. In such a case, I think torch should not point to anything like how torch.utils is not linked to anything.

To Reproduce

# test.py
import torch.utils.data

class MyDataLoader(torch.utils.data.DataLoader):
    pass

<!-- docs/index.md -->
::: test.MyDataLoader

# mkdocs.yml
site_name: Test

theme:
  name: material

plugins:
  - mkdocstrings:
      handlers:
        python:
          import:
            - https://pytorch.org/docs/1.10.1/objects.inv

nav:
  - Home: index.md

System:

• mkdocstrings-python version: 0.7.1
• Python version: 3.9.12
• OS: MacOS
