unSelectAll not working on single select dropdown with placeholder

[hobwell]

With a single select dropdown (containing a placeholder) unSelectAll does not clear the selection and re-display the placeholder, which is the behavior I would expect.

Using unSelectItem(<idx>) did the appropriate thing (clear selection, re-display placeholder), but using unSelectAll should do the same without having to know the selected index.

Please see the fiddle .

To get the placeholder to appear at all I had to include the 'size' attribute on the select tag (which may be a separate issue).

This should be fixed in v3.3.7
