Imho returning the empty value would be correct here, but I guess that might break other stuff in piwik to change that behavior.
If you think it would be correct behavior, maybe it's worth trying the correct fix and see if all our tests would still pass? it may be a bit risky but in general it's worthwile trying the "Correct fix approach" in case it may just work :-)
And kuddos for this PR! :+1:
Maybe we should not try to do that for a minor fix version.... But I could try to change that after 2.14.1 was released.
Makes sense to limit risk for 2.14.1 :+1:
looks good, thanks for looking into this regression @sgiehl
