This sounds like something that was fixed in commit b99848c72cb2570c 
(meaning, about a year ago).

I have tried to quickly reproduce this in my build from master, and 
hadn't managed to.

How recent is Emacs that you're trying this in? Do you perhaps have an 
older version of project.el or xref installed through ELPA?

Or did you maybe use project-switch-project, doing a search from its 
menu, like Sean seems to be hinting?
