The issue here is that the onload handler executes _before_ the window title is
set from the "title" attribute (thus giving you a chance to change said
attribute in your onload handler).  If you have to write to window.title
instead, just put it on a timeout...

Do you mean that it's more feature than bug? It's not clear feature because when
load event is called then I mean initialization has finished. But window title
was not be setted.

Yes, we use that code pattern ourselves, but also this one:
document.documentElement.setAttribute("title", newTitle);
(obviously this only applies in the onload handler)
And another way that works is not to set the title attribute, e.g.
<window onload="title='foo';"/>

What Boris describes in comment 2, I'd call a bug. It's an unfortunate side
effect of the fact that we ourselves set the window title in the load handler.
We should consider not setting the window's title from the title attribute if
the window's title has already been set before our load handler runs.

As from 1.8a4 setting document.title should now work.
