I haven't tried running a fix yet, but I'll bet this is the bug: the search
through m_proposed databases uses '==' to compare the SecurityOrigins, but it's
stored a threadsafeCopy, so a pointer comparison always fails.  It should be
using SecurityOriginHash to compare them.  I'll go get set up to test a fix.
