Using Raven 1.1.15: 1. Load Raven 2. `Raven.uninstall()` 3. `setTimeout(function () { throw('oh no'); }, 0);` Expected: Native browser error handling Actual: `Error: Raven has not been configured` thrown in Raven-wrapped function Looks like the functions `setInterval` and `setTimeout` are overridden by `extendToAsynchronousCallbacks` but never properly restored.
