Skimming the code there, it seems like xref just gets a list that it
inserts into the buffer, and then applies the invisibility spec to the
long lines?  That's a bit different from what compilation-mode/grep is
doing, where a process inserts text.  I.e., invisible text, in general,
works fine, but there's some bad interaction between
processes/invisible/font-lock somewhere.
