Steps to reproduce

It seems to happen intermittently, and haven't fully figured out why/where it occurs. Here's an example of an MDX document that reproduces the error:

# Example document

- [Link](/a)
- [Link](/a)

Expected behavior

Doesn't error, or at the very least does so silently.

Actual behavior

It errors, and once it gets going, does so repeatedly.
