Issue:
sphinx.errors.NoUri
### Describe the bug

**context**
I don't know whether this error relates to MyST-Parser, but I began getting this error after MyST-Parser 0.19.0 was released.

**expectation**
I expected no errors like my previous builds with myst v0.18.1.

**bug**
But instead, the `sphinx.errors.NoUri` error happens after myst v0.19.0 was released.
https://readthedocs.org/projects/deepmd/builds/19635616/
https://readthedocs.org/projects/deepmd/builds/19635930/
https://readthedocs.org/projects/deepmd/builds/19647300/

Here's an error message I ran into...

**problem**
Indeed I don't know the reason.
