The piece of feedback I have is that this logic could probably move to the
TabContents rather than being duplicated in every one of the TCVs.

I can do that, but we still need to add something like the following for every
one of the TCVs:
  tab_contents_->UpdatePreferredSize(pref_size);

Unless we want to move UpdatePreferredSize from RenderViewHostDelegate::View to
RenderViewHostDelegate. Which way do you prefer?

+    tab_contents_->delegate()->UpdatePreferredSize(tab_contents_, pref_size);
 }
