Noticed by jya in bug 1630211, this bug has been filed to investigate those errors.

This code is run in an idle callback, so I expect the PiP code just needs to deal with the case where the window root has gone away by the time it fires. That said, this doesn't seem like a severe bug nor like something that'd break anything else, given it runs in an idle callback...
