UnexpectedValueException: Expecting non-empty $root_file_path and $checked_file_path

[M393]

This error is logged occasionally when hovering elements with the VSCode extension. This time it repeatedly happened when hovering over a specific call to file_get_contents. Other elements worked fine. Making a change and reverting sometimes 'fixes' it.

7246 seems to describe a similar problem, but in my case it doesn't seem related to live typing as it happened repeatedly, even when the file is not changed for some time.
