Cannot regain focus on the content area by clicking on it if it's empty in IE6

Here are the steps I took:

• Launch IE6
• Go to a XE 1.8 post RC1 wiki (XWiki Enterprise 1.8-SNAPSHOT.17107)
• Create a new page
• Switch it to XWiki 2.0 syntax
• Edit it with the new WYSIWYG editor
• Once the page is loaded, click outside the content area before adding any content
• Try clicking on the content area again: focus doesn't come back, the cursor has disappeared
• The only way to get the focus back is to click on one of the WYSIWYG's buttons (bold, italics...)

Clicking on the content area when it's empty should bring the focus back and display the cursor in IE6.
