           Summary: Initial call to webkitRequestAnimationFrame returns 0,
                    Spec indicates the handle should always be > 0
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: UNCONFIRMED
          Severity: Minor
          Priority: P2
         Component: WebKit API
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: ctrlfrk at hotmail.com


Looking at http://www.w3.org/TR/animation-timing/ there is a section that reads: "The requestAnimationFrame method is used to signal to the user agent that a script-based animation needs to be resampled. When requestAnimationFrame(callback) is called, the user agent must schedule a script-based animation resampling by appending to the end of the animation frame request callback list an entry whose handle is a user-agent-defined integer greater than zero that uniquely identifies the entry in the list and whose callback is callback."

However the first call to webkitRequestAnimationFrame seems to be returning a handle of 0. 
It's minor, but worth mentioning.
