511151 - Cursor can fail to change shape loading a new page (Windows)

Status: RESOLVED WORKSFORME

(Core :: DOM: Events, defect)

Description

[Steven Michaud [:smichaud] (Retired)]

This Windows-specific bug is spun off from bug 510919, and seems to be
unrelated to it, though the symptoms are similar.  It happens on the
1.9.1 branch and above.

STR:

1) Click on a link to this bug's URL
   (http://www.coteindustries.com/articles/html_articles/tabindex.html).

   Be careful not to move the mouse as you click on the link.  If you
   move it enough to change it to a pointer before the new page has
   finished loading, the bug doesn't happen.

2) A new page will load, but the mouse cursor will fail to change from
   a hand cursor back to a pointer.  It only does so when you move the
   mouse.

Bug 510919 comment #1 suggests this regression may have been
caused/triggered by the patch for bug 481359.  This seems to be true
-- backing out the patch for bug 481359 stops this bug from happening.
You can see this for yourself by testing the following tryserver build
(which backs out the patch for bug 481359 in current code):

Isn't this the same as Bug 482985 ?

It sounds related.  I'm not sure it's a dup.

Markus, what do you think?

I could not reproduce the issue on Windows XP on the latest Firefox 46 RC and on the latest Nightly 49.0a1.
