I'm not sure what you mean by that? We did use `issue.get().title()` in lots of places, but I replaces them with `issueTitle `to only have a single strip. That's as close to the source I can see possible.

Yeah, my bad... i commented out the test before while developing to speed up the re-run time. Didn't realize this changed the behavior when bringing it back. Will fix.
