102054 - boxes with same ordinal isn't ordered correctly when dynamically changed

Status: NEW

(Core :: XUL, defect, P4)

Description

[Jonas Sicking (:sicking) No longer reading bugmail consistently]

When ordinal is dynamically changed boxes with the same ordinal isn't ordered in
content order.

Steps to reproduce:

1. go to the supplied url
2. set ordinal 1 for all buttons
3. repeatedly set the ordinal to 1 for the fist button

Actual results:
Once all boxes has ordinal 1, setting it to 1 (again) will move the button to
last position.

Expected results:
When all buttons has ordinal 1 they should always be ordered in content order
(which is 1 2 4 3 in the testcase)

This issue was discussed prior to landing the ordinal stuff, so see the
discussion at the end of bug 93519.  To summarize, this behavior would be nice
to have, but could potentially complicate and slow-down the box sorting code, so
I am not sure if it is worth it.

so what should we do with this, IMHO we should either change the spec or try to
fix this bug

the tradeoff is that instead of (potentially?) complicating and slowing down the box sorting code, the application developer has to iterate and rearrange dom nodes from javascript to guarantee correct display order, after updating ordinals.  i'm sure that's even slower.  and it makes ordinals less useful.
