Unable to cleanly exit F11 fullscreen in Chromium under Maximus

Binary package hint: maximus

I am using Chromium (11.0.696.68 (84545) Ubuntu 10.04) under Netbook Remix in conjunction with Maximus. I have Chromium preferences set to "Use system title bar and borders". When I press F11 to get fullscreen this works as expected. However, when I press F11 a second time to exit fullscreen, I am left with a Chromium instance that is (a) no longer maximized (b) has no borders or title bar and (c) is perpetually "on top". The only way to proceed from here to return the desktop to normal is to exit Chromium.

Unsure if this is a Chromium or Maximus bug?
