Can you ensure that this does not create a problem if your patch includes a
vulcanized/crispified file? Or if it does, is there an easy way to bypass?

I guess this is done only for files under ui/webui/resources (even if the CL has
other files too), but it is worth double checking.

[Dan Beam, 2016/12/22 00:59:54]

right, there are no crisper files in ui/webui/resources
