            Bug ID: 265934
           Summary: [web-animations] effect targeting an element with
                    `display: none` should not schedule immediate
                    animation resolution (affects reddit.com)
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Animations
          Assignee: webkit-unassigned at lists.webkit.org

If an effect targets an element with `display: none` it will currently schedule immediate animation resolution. This affects reddit.com which chews a lot of CPU scheduling animation frames at 60Hz while not performing any visible animations.
