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.
