597576 - window.open appears to open popup with wrong size/position and then move/resize

Status: VERIFIED WORKSFORME

(Core :: Widget: Win32, defect)

[Duncan Loveday]

User-Agent:       Mozilla/5.0 (Windows NT 5.1; rv:2.0b6pre) Gecko/20100917 Firefox/4.0b6pre
Build Identifier: Mozilla/5.0 (Windows NT 5.1; rv:2.0b6pre) Gecko/20100917 Firefox/4.0b6pre

In the Firefox 4 beta a call like

window.open('test.html', 'test', 'top=100px,left=100px,height=200px,width=300px');

opens the popup with a size and position that differs from the given values and then immediately resizes and moves the window to the specified position. The effect is most noticeable when the parent window is maximised at the time the window.open() call is made.

Firefox 3.x just opens the popup in the right place.

Is that a bug ?


Reproducible: Always

Steps to Reproduce:
1. Load the test case
2. Maximise the firefox window.
3. Click the button and observe the behaviour of the popup.

Actual Results:  
Popup appears at one position and size and is then moved and resized.

Expected Results:  
Popup should appear with the correct position and size right away.

Maybe duplication of Bug 594881 or Bug 595811

Bug 594881 has to do with restoring a size mode, so that really doesn't fit this. I think this has to do with sporadic size events sent to the window from the view prior to chrome being loaded.

There is another similar bug, I mentioned this in bug 582755 comment 4

confirming, as there's a testcase and it's already been marked blocking.

A new fix landed in bug 574690 that should address this.
