            Bug ID: 216385
           Summary: Web Inspector: Uncaught Exception: Animation domain
                    already tracking (at Connection.js:​162:​29)
           Product: WebKit
           Version: WebKit Local Build
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Web Inspector
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: bburg at apple.com
                CC: inspector-bugzilla-changes at group.apple.com

STEPS TO REPRODUCE:
- navigate to brrian.org
- open inspector to Timelines tab, with Media & Animations timeline enabled
- navigate to nfl.com
- Uncaught exception "Animation domain already tracking (at Connection.js:​162:​29)"


seems like animation instrumentation is auto-starting, or has bad initial state upon cross-domain navigation. I wonder if it happens on a same-domain or same-document navigation?
