[oc-basic] fontification weirdness

[Bruce D'Arcus]

I can't fully pin this down, but I and a couple of others I've
discussed this with are seeing the following behavior.

With this example:

a citation [cite:@couper2014] and another [cite:@kohn2006]

... the first citation is highlighted, and the second (and any
subsequent) is not.

In some way I can't reproduce, I can then get the fontification to
work correctly, but if I restart, the problem reappears.

Discussed more here:

Can anyone else confirm this?
