This test illustrates the problem that the autocompletion in the DevTools Console does not properly cancel previous attempts.

Steps

1. Open DevTools
2. Reload the page
3. Observe that you're paused on a debugger statement in foo afterwards
4. Type foo8 and observe that the autocompletion will suggest foo8etch and other hits for a short period of time
