Build ID: 2004-07-10-08, Seamonkey trunk on Windows XP, but this has been seen
by biesi and dbaron on Linux.

Summary: Tiny empty tooltip appears seemingly random when loading a page.

This is a new regression in today's 2004-07-10-08 build.

Steps to Reproduce:

1.  I'm not sure just yet, but loading pages (no user events are necessary)
seems to trigger this.

See screenshot.

<stephend> dbaron, so, more research shows me that it's something related to
TITLE attributes
<stephend> and also, that it is drawn in a straight line above the mouse pointer
<stephend> (at least on windows)
<stephend> (I mean title attributes)
<stephend> because composer is registered to edit HTML files?
<stephend> something isn't killing tooltips per-page.
<stephend> I'm loading other pages, and seeing previous tooltips bleeding over

Fallout from bug 91312 perhaps?

My Spidey senses tell me bug 91312 is a likely culprit.

I've done:

cvs update -j1.30 -j1.29 mozilla/xpfe/browser/resources/content/browser.js

followed by a top-level make chrome in C:\moz_src\mozilla, and that cured both
of my ails.

cc:ing [e-mail] (author) and timeless (patch lander),
for now.

(assigning, rather, since I should follow Brendan's directive)

This bug always appears for me whenever I go to (domain.com):5800 to look at a
VNC server.

Unfortunatelly I'm not talking currently from a place where I can debug this, but nor can I see how my patch could ever cause this regression.

Could you please try adding my patch again, but then removing this line:
tipNode.style.direction = direction;
?
I wonder if it fixes your problem. If so, it's still some kind of a bug with the TOOLTIP XUL element, but at least we could narrow it down.

Commenting out the assignment to direction seems to fix it also (leaving intact
the other two lines 1) +  var direction = "inherit"; 2) + 
tipNode.style.direction = direction;)

I backed bug 91312 out of the trunk so that we can progress towards shipping 1.8a2.
