I have these in my readme.md:

locally (MacOS) my build has no errors

on CI (linux ubuntu)

Generating doc/file.README.html⢿ Generating doc/file.README.html.[warn]: In file `README.md':275: Cannot resolve link to the from text:
	...{the <code>foo-</code> bar}...

the offending code is:

[the `foo-` bar](https://example.com/Path#fragment)

the yard and ruby versions are the same in both places

what could cause the difference in behavior?
