1005947 - onresize event is fired twice

Status: UNCONFIRMED

(Core :: DOM: Events, defect, P5)

Description

[Prashant Hiremath]

Attachment: onResize.html

User Agent: Mozilla/5.0 (Windows NT 6.1; rv:29.0) Gecko/20100101 Firefox/29.0 (Beta/Release)
Build ID: 20140421221237

Steps to reproduce:

I have registered onresize event on body tag, whenever i resize(maximize/RestoreDown) the browser window onresize event should be fired.


Actual results:

onresize event is fired, but rather than firing only once it is fired twice whenever i maximize or Restore Down my browser window. So 
1) on Restore Down Browser Window : onresize event is fired twice.
2) on maximise Browser Window : onresize event is fired twice.



Expected results:

onresize event should have been fired only once i.e once for Restore Down Browser window and once for Maximise Brower window.

Chrome Browser behaves normally and fires event only once.

What are the window sizes (innerWidth/innerHeight) you see before you maximize and during the two event firings?

Hi Boris, 

window size before I maximize are :

innerWidth:1066 innerHeight:551

When i maximize window in both the events I'm getting same innerWidth and innerHeight i.e

innerWidht:1440 innerHeight:789
