Autocomplete still overlaps text field in Firefox

I just downloaded and tried the 4.2 GA version of woodstock, but with disappointment I see that this has not been fixed yet.
If you use the autocomplete feature of a text field, the list of choices that appears when you start typing overlaps with the text field itself, in Firefox.
Am I the only one experiencing this? I tried to file a bug issue but with no reply yet.

In my opinion this is a big adoption blocked for components in Firefox

thanks
