500826 - does panel widget's autoPosition property works?

Status: RESOLVED INCOMPLETE

(Toolkit Graveyard :: XULRunner, defect)

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; es-ES; rv:1.9.0.11) Gecko/2009060215 Firefox/3.0.11
Build Identifier: XulRunner 1.9.1

While working with an always visible <panel> (noautohide="true") I was trying to get rid of the default behaviour of a <panel> to always reposition itself to be always visible when it's parent window is moved (I don't want this repositioning to happen). I found an autoPosition property and decide to give it a try, I found a couple of things that made me file this bug.

Reproducible: Always

Steps to Reproduce:
Considering the following piece XUL code:

...
<panel id="top" noautohide="true">
 <vbox id="top_menubar">
  <toolbarbutton id="choose_group" label="Home" menu="popup_groups" />
 </vbox>
</panel>
...

Actual Results:  
If you put the following js sentences the panel will be displayed:

let toppanel = document.getElementById('top');
toppanel.openPopupAtScreen(window.screenX, window.screenY, false);
toppanel.autoPosition = false; // <-- at this point coordinate set in previous sentence is lost, panel will be rendered at (0, 0) of main window from now on.
toppanel.moveTo(400, 200); // <-- this is ignored and any attempt to change panel's position will be ignored too (with means like setting css margins, top, left props for example)

placing toppanel.autoPosition=false before opening the panel does not seems to do anything either, moveTo sentence is ignored too.

Expected Results:  
I was under the impresion that autoPosition=false would allow me to position the panel freely (that is, without any automatic positioning triggering) but that wasn't the case. I wonder what is the intended usage of this property. I think autopositioning of panels is a good thing but it showld also be a way to disabled default behaviour.

As a sidenote I'm working with a title-less window and I'm trying to do a toolbar which includes a custom titlebar and buttons above the main window. It actually works as long as you stay away from the screen edges (which triggers a rather annoying autoposition dance in the panel).

XULRunner has been removed from the Mozilla tree: see https://groups.google.com/forum/#!topic/mozilla.dev.platform/_rFMunG2Bgw for context.

I am closing all the bugs currently in the XULRunner bugzilla component, in preparation for moving this component to the graveyard. If this bug is still valid in a XULRunner-less world, it will need to be moved to a different bugzilla component to be reopened.
