           Summary: An 'onchange' event is not triggered on a multiple
                    file form when selected files are changed
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Forms
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: haraken at google.com

Assume the following form:

<input type="file" name="file" id="file" multile="multiple" onchange="alert(100)" />

(1) Click "Choose Files", select 1.jpg and 2.jpg, and click "OK".
(2) The 'onchange' event is triggered.
(3) Again, click "Choose Files", select 1.jpg and 3.jpg, and click "OK".

Expected behavior: The 'onchange' event is triggered.
Actual behavior: Nothing happens.

Accurately, the 'onchage' event seems to be triggered only if the first item of newly selected files is same as the first item of previously selected files.
