cubicweb #8602446 weird cursor after ajax request [validation pending]

When the 5th parameter (cursor) to loadxhtml is set to true, the cursor does not go back to normal when the AJAX call is finished. E.g, after editing and submitting a comment on the forge, the cursor on text is no longer the usual cursor (a capital I like cursor). Instead, the standard cursor is used.

The underlying issue is with setProgressCursor() and resetCursor(). The latter does not use the correct syntax to properly reset the cursor to its default value.
