Using the web inspector makes JS very slow Steps to reproduce: 1. Go to http://nerget.com/rayjs/rayjs.html 2. click render *eat candy until it's complete, it will give you a time* 3. "Inspect Element" on the document to open the inspector 4. close the inspector 5. click render *eat more candy* This second run is between 10% and 25% slower than the first :(, but lets continue 6. Open inspector again, switch to resource view, then switch back to element view and mouse over a few elements, then close inspector. 7. click the render option again this time round i see something in the order of a 50% regression From now on all JS in that webview will run really really slowly unless you close the tab/window -- other webview appear to be unaffected.
