auto_complete_field does not update display:none

Hi,

text_field_with_auto_complete works.

auto_complete_field almost works, the only problem is that it does not update the display:none default attribute of the div that receives the results. So the results are there, but I can't see them.

I compared both html, and they look the same. Only CSS differs, but updating the display:none should only happen in the javascript code.

Who ran into that issue and managed to get rid of it?
