Exception lines are not correctly linked

[cursive-ghost]

Reported by @kennyjwilli in Slack:

Cursive doesn't always correctly link line numbers in exceptions. For example, I'm in a project that contains compute.db.formulas namespace. The below exception highlights everything except the calls from that namespace.

It appears to have to do with the fact that the files are .cljc and not .clj.

Another example. diff-projects namespace is in my current project and it is not linked in the below stacktrace.
