Do you mean it will only return matches in files in that directory,
even if ID says the file is elsewhere?

I cannot answer that without understanding the meaning of the prompt.

If you type "lid", do you see absolute file names in both cases, or do
you see relative ones when ID was created by "mkid ." (note the dot)?

If you tell me that "lid" returns relative file names, and
xref-find-references still work, I will see if this is something
specific to Windows.

I didn't say xref should fix this.  Is there no information  xref gets
from symref apart of the (empty) list of references?
