           Summary: Cursor change fires mousemove event
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
               URL: http://jsfiddle.net/TRF7g/
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Event Handling
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: davidbarr at chromium.org


Upstream bug: http://crbug.com/103041

Simple reproduction:
http://jsfiddle.net/TRF7g/

Ran bisect-builds, bug present in WebKit since at least r37376.

-- Original report --

Chrome Version       : 16.0.912.21
OS Version: OS X 10.6.8 (also checked windows7)
URLs (if applicable) :
Other browsers tested:
Add OK or FAIL after other browsers where you have tested this issue:
     Safari 5: FAIL
  Firefox 4.x: OK
     IE 7/8/9: FAIL*

What steps will reproduce the problem?
1. Create an event listener that is triggered by 'mousemove'
2. Change the cursor either with a CSS class change or element.style.cursor
3. Observe the event listener

What is the expected result?
Cursor changes without firing a mousemove event.

What happens instead?
Cursor changes and a mousemove event is fired.

Please provide any additional information below. Attach a screenshot if
possible.

Seems like it may be a webkit issue since Safari behaves exactly like Chrome for this issue. 
*IE9 (haven't tested others) does not change the cursor until the user moves the mouse (this also seems incorrect.)
