xfce panel window buttons not disappearing when window is moved to a new viewport (Compiz)

Description

I've experienced an issue when using Compiz 0.9 with the Xfce Panel.

Say I have a window open on workspace 1 (viewport 1 in Compiz terms). If I right click on the window's titlebar and choose 'Move to Workspace Right' then the window will move to workspace 2 but the window button will still be visible in the panel in workspace 1.

If I then switch to workspace 2 and then back to workspace 1 then the window button will have disappeared from the panel in workspace 1 like it should.

In essence, the panel needs a viewport switch before it updates the positions the positions of window buttons for windows that have moved to a different viewport.

I first experienced the problem in Xfce Panel 4.10.1 (the issue might be older than that even) but I can still reproduce the problem with Xfce Panel 4.11 (I built the 4.11 version from the latest git source a couple of days ago to test).

As for Compiz, I'm using 0.9.11 from the bazaar repo.

Version: 4.12.0
