Windows without scrollbars seem not to get blur events. This is of course not
generally a problem for most web pages, but for popup windows. Actually it's
concealing a crash bug 68454 right now, so I kind of appreciate it. But it's an

Also note that the attached test cases will demonstrate that we get too many
focus and blur events in windows with scrollbars. That's a different bug 164686.

It's worse than I thought: a window without scrollbars doesn't even get focus
events. It fakes one every time you click in the document (regardless of whether
the window (and document) are already focused). But the window never gets a
focus or blur event when the user repeatedly blurs the window and reactivates it
by clicking outside the document; in the titlebar, say.
Summary: blur events not executed in windows without scrollbars → focus & blur events not executed in windows without scrollbars

I pretty sure it is a same with bug 190767, because my patch fixing it :-). Yes,
it seems that window without a scrollbar lose an events, as in bug 190767 do
frame with scrolling=yes.

I have no idea why scrollbars have anything to do with this, or when it regressed!

If I correct, source of this bug is that window without scrollbars do not
generate Content for Element, give to and bug 185889 clear target frame for this

P.S. regression happened after Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.3b)
Gecko/20030114, but I pretty sure that it is patch for bug bug 185889 fault.

O'k. I do following: I remove patch to bug 185889, and test it -- onfocus and
onblur work correctly. Then I add patch to bug 185899, and this bug appeared
(counters was 0/0 when I switching windows). So I think this bug is bug 185889
regression, and hereby dupe of bug 190767.

Excellent! Thanks for taking a look, Ruslan. I think this bug's current status
as dependent on 190767 is better than closing it as a duplicate, because the
symptoms described are so different.
