125421 - select form control restores selections on back based on element's position

Status: RESOLVED DUPLICATE of bug 95622

(Core :: Layout: Form Controls, defect)

Description

[Christian Reis]

Problem (assumes you have a select control in a submittable form, such as
query.cgi):

have a select form control with MULTIPLE
select a number of the form control's elements
submit form
press back button

Results:
control's contents are restored. This is expected. However, the problem lies in
the fact that they are restored based on their original _position_ and not their
_contents_. This usually isn't a problem _unless_ the select control is filled
in dynamically, in which case the wrong selections will be restored.

This is a pretty tricky bug to reproduce, but because Bugzilla's query.cgi is
the select control burn-in test, we've uncovered it.

jkeiser has given me some feedback on it, and i'm looking at the code
