EXT-7505 FIX stuck in appearance edit mode if close appearance sidebar

Added a check for visibility changes that should prevent users from getting
"stuck" in appearance editing mode by closing the appearance editor
prematurely (clicking sidebar hide, etc).

Camera state should be restored when panel is restored.
