Description of the bug

Currently we ignore identifiers that contain a space or a slash. This is problematic because object inventories allow spaces and slashes in object names. For example we find the following entry in Python's object inventory:

type hint std:term -1 glossary.html#term-type-hint -

Here type hint is the identifier that we would use to reference the glossary.html#term-type-hint page and anchor.

To Reproduce

In a MkDocs project, enable the mkdocstrings plugin, and load the Python objects inventory with std and py domains:

plugins:
- mkdocstrings:
    handlers:
      python:
        import:
        - url: https://docs.python.org/3/objects.inv
          domains: [std, py]

Add the following cross-ref to your pages, observe that it isn't resolved and rendered:

Link to [type hint][].

Expected behavior

Cross-ref should be resolved.
