Content of 2.0 {{column}} macro is not editable in WYSIWYG mode

Paste the following code in a page :

 
{{section justify="true"}}
{{column}}
content of column 1
{{/column}}
{{column}}
Content of column 2
{{/column}}
{{/section}}

Correctly rendered, but if you try to edit the page in WYSIWYG mode, you won't be able to edit the content of the section elements, only property "justify" is available (in "edit macro properties").
So you are forced to edit using wiki mode.
