plus my post over there
Yes, this is a known issue
There’s https://bugzilla.mozilla.org/show_bug.cgi?id=934624 for it
We might get to it when we implement “Search in all files” (https://bugzilla.mozilla.org/show_bug.cgi?id=889571), which might happen in the coming months
Encouraged to hear this is likely to happen - thanks and sorry to be asking about a known issue (I tried to find it here but didn’t spot I could have looked at the bugzilla subdomain, I’ll check there too in future ).
