143081 - incorrect <option> selected when list changes on reload

Status: VERIFIED DUPLICATE of bug 46845

(Core :: DOM: Core & HTML, defect)

Description

[Jason Pfeil]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0rc1) Gecko/20020417
BuildID:    2002041717

When the list of options in a <select> on a form changes and the page is
reloaded (without the shift key being depressed) Mozilla selects the opition
that is now in the the .selectedIndex position that was current before the
reload, instead of the <option selected> item of the current page.  So, if one
item is added to the list above the selected item, then the page reloaded, the
selected item is off by one (one too high) and vice versa.

Reproducible: Always
Steps to Reproduce:
1. download mozilla_bug.tgz from url given in this bug report
2. extract into: mozilla_bug.html mozilla_bug1.html mozilla_bug2.html
3. load mozilla_bug.html
4. # rm mozilla_bug.html; ln -s mozilla_bug2.html mozilla_bug.html
5. click Reload in Mozilla (you'll see the selection off by one)
    - view source and see that opt5 should be selected.

Actual Results:  Off by one in the select box

Expected Results:  Select box should have the <option selected> item selected,
not the one equivalent to the previous value of the .selectedIndex property.
