Just a note that after discussing this with Charlie last week, I went ahead and
added this optimization in PS6 to only send WebFrameOwnerProperties to new
proxies when they're different from default values.  No need for this IPC in the
default case, as WebRemoteFrameImpl::createRemoteChild already initializes the
FrameOwner with default values.

Acknowledged.
