(Camino Graveyard :: HTML Form Controls, defect)

I suppose it has to do with the call to scrollIntoView();
After experimenting with the examples funcions, the select element's drop down
list does not get displayed at it's propper position any more.
It seems to get "scrolled away" with the page

Reproducible: Always
Steps to Reproduce:
1. go to
http://www.din.or.jp/~hagi3/JavaScript/JSTips/Mozilla/Samples/ScrollIntoView.htm
2. use the example's controlls to scrollIntoView the different boxes.
3. see where the drop down list gets displayed next.

Actual Results:  
drop down list's position becomes detached from the select element

Expected Results:  
...

Definitely shouldn't do that, and I'm seeing it as well with 20040330. The 0.8
Firefox release shows the correct behavior

Not a dupe. This is actually just due to having the select in a position:fixed.
The menu thinks that it's scrolling with the page.

Attachment: reduced testcase

Scroll around; the select is fixed but the menu thinks it should be moving.

I think this bug was meant for HTML Form Controls, not History :-)
