           Summary: ScheduledAction may be deleted during execution
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Bindings
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: barraclough at apple.com

For one-shot timers we move ownership of the ScheduledAction to a local RAII variable, so they'll survive until timer fire completes.

However for interval timers the ScheduledAction remains owned by the DOMTimer, which could cancel itself from script.

Change ownership model of ScheduledAction so even if the DOMTimer is cancelled the ScheduledAction won't be deleted mid execution.
