Firefox: Hiding/Displaying CKeditor causes caret to disappear

[mtyson]

Problem: If you set the style to display:hidden and the display:visible on the element containing the CKEditor instance, when the editor is visible again, the caret is not visible. Typing still enters text.

Firefox only.

Steps: 1) Create ckeditor instance 2) On the dom element containing the instance (the instance parent - this might work on the instance itself also), set style display:hidden 3) Set display:visible 4) Type in the editor - notice the caret is not visible
