Description David Kilzer (:ddkilzer) 2021-03-26 15:56:41 PDT 
WebFeature class fails to copy/retain its instance variables despite what its @property declarations state.

To fix this, I'm just going to add -copy methods in the init method, and add a -dealloc method that can be deleted when switching to ARC.

Using RetainPtr<> for this class seems overkill.

Patch v1

I think Chris is trying to use RetainPtr everywhere, so we probably should here too, but you don't have to in this patch. I can do so in a follow up.

Those were some speculative fixes to try to resolve some CoreIPC crashes if I remember correctly.  I appreciate you offering to follow up on this.
