I'm not really familiar with html_viewer, but I'm wondering why these properties
are included here?  This looks similar to content's FrameReplicationState, and
we didn't include these properties there, as we didn't want them to be
replicated for all proxies, right?

I've reverted this change and added a TODO.
Yes, we do not want to replicated them in remote frames.
