Usually when you delete a crbug # in a CL that's a good sign you should add it
to the BUG= line of the CL description :)
But in this case 91512 looks kinda ambiguous; did it get silently fixed by a CL
that didn't point to it?
If yes, please add BUG=91512 to the CL description, add a pointer to the fixing
CL to the bug, and mark the bug closed.
If not, and this never really needed to wait for 91512, then please remove the
empty BUG= line from the CL description.
