Setting frame focus, in Javascript it is called "focus()", does not work. I have
made three slightly different testcases.

I think that frames should be able to change other frames and the frameset, or
am I wrong? I remember they did in earlier versions of Mozilla. Maybe it is
related to http://bugzilla.mozilla.org/show_bug.cgi?id=202955 Please also
consider that self.document.title=self.right.document.title does work, see
testcases! That is inconsistent.

What happens if you don't call this onload?  The issue is that Mozilla itself
has an onload handler attached to the toplevel frameset; this handler focuses
the frameset.  This fires after all the frames' onload handlers, of course...

A standard frameset, without addditional "onload"s, focuses on none of its
frames, see frameset4.htm in testcase directory! Scrolling with page up and down
does not work unless one clicks with the mouse in a frame. 

>This fires after all the frames' onload handlers, of course...

Obviously but not naturally. It could focus itself just after initialization of
the frameset, just like framesetless windows focus themselves after window
initialization.

As I said that _could_ be the problem. It may not be.  Does calling the focus()
function on a button press instead of onload work?  I'm just trying to establish
the scope of the problem before I start trying to look for code to change... ;)

No: http://grassomusic.de/testcases/frames_focus/frameset4.htm

Yeah, even changing that input to type="button" does not work.  bryner, any idea
what's up here?

Ok, the bug appears to only happen when an alert() is used before the focus
call.  Just a guess, this is probably focus memory restoration racing with the
second .focus() call.  Confirming and taking.

Not on my machine. I erased the alert call in the testcase (and changed the type
to "button", yes!) so everyone can try out.
