Field of type hippo:query cannot be removed from template

• create a document type
• edit the document type
• add a hippo:query field
• click on the 'remove' icon
• nothing happens

It doesn't look like a serious issue, but consider this: if you just added 15 fields to your template, filled in the names and paths, then add a hippo:query field and find out you cannot remove it, you are not happy. The template you just spent an hour on has just been made useless, you have to start over.
