WYSIWYG Editor cuts off content in full screen mode

Use a Moodle site with the fix installed, verifying that TinyMCE is enabled and has the highest priority. In all core dock-enabled themes (Afterburner, Anomaly, Overlay, Splash, Standard) Create a test course using the development tool. Navigate to a discussion forum and either reply to or create a new thread. Verify that the text editor in use is TinyMCE. Minimize one or more blocks into the dock at the side of the screen. Switch the editor into fullscreen mode. Verify that the dock is no longer visible. Exit fullscreen mode. Verify that the dock is once again visible.
