Fix a bug where we get an extra resize event for background tabs.

The TabContentsContainerGtk is a GtkFixed that contains a
TabContentsViewGtk for each tab.  We hide the background TCVG
and only show the foreground TCVG.  However, when the TCCG
gets a resize event, we were still sending a set_size_request
to all the background tabs.  Since they were hidden, nothing
happened except in the case described in issue 14114.  It
seems like this is a spurious resize by gtk, but not sending
the resize request seems to work around it.
