I think we could filter on the label even if it is not in the displayed
string, or append it to the string for the outliner, then you could
filter on that, too. 

I just think having 15 entries which all look the same is not very
helpful when trying to navigate to a specific cross reference.

In any case, there is a drawback in your change: the string is
truncated before it gets passed to the outliner. We don't do that with
other entry types, and it also affects filtering, as only the
untruncated part is considered.

I fixed this in master. Feel free to cherry-pick (or revert if you
disagree).
