Status: RESOLVED INVALID

Test case at URL provided has Content-type text/plain.

The document loads and the menulist appears to have the first option selected by
default. (Indeed this is the case on the Linux platform, possibly others.) If
one tries to access the value of the selected item (or simply the value of the
first item in the list) 'undefined' is returned. Once a selection has been made
either by user input or the 'selected' attribute, behavior is normal.

Reproducible: Always

You can't guarantee that XBL bindings exist for invisible elements.
Also, you should be using menulist.value to retrieve the value.
Also, you should use <script> in preference to <html:script>.
