           Summary: WebKit transition callback doesn't fire if CSS
                    property did not change during the animation
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
               URL: http://jsfiddle.net/NpdcJ/
        OS/Version: Unspecified
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: CSS
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: andrej.okonetschnikow at gmail.com


If during a CSS transition all CSS properties applied to an element remain unchanged the transitionEnd event will never be fired.

Expected: the transitionEnd event should fire even if CSS properties remain unchanged.

Please find here a test case: http://jsfiddle.net/NpdcJ/

It might specially occur if CSS properties are set programmatically and not through CSS classes.

As a workaround one can set translate property with sub-zero properties (0.01px) to invoke a transition. Here is an example with a workaround: http://jsfiddle.net/GX7jz/
