BUG #13863: Fix visibility animation.

When animating visibility, we were turning on visibility of *all*
representations, including those that were added as subproxies to some other
representations. Hence all the representations ended up being visible are
indicated in the BUG #13863. This fix address that issue by skipping toggling of
visibility for sub-proxies.
