Setting the title attribute of the window XUL element does not change the title in titlebar. Same with the root element of other window types like dialog or wizzard. The attribute value is changed, but the titlebar is not updated.

The string in the titlebar remains what originally was written in the XUL document, but does not update, when the title attribute is modified via JavaScript.

Reproducible: Always

Steps to Reproduce:
document.documentElement.setAttribute('title','Bug');

should set the titlebar of the window to "Bug", but only the attribute value is changed not the title displayed in the titlebar, which remains untouched.

I believe the correct way to change the title is:
document.title = "Bug";

Comment 2

[Georg Maaß]

using document.title = "Beetle"; works also in XUL. I assumed this being correct only for HTML. If this is the official way for XUL too, then this is OK for me.

Setting bug to INVALID, because trying it the wrong way is my fault.
