Steps to reproduce the problem:
1. Set a breakpoint in code and stop at the breakpoint

IMPORTANT -- Make sure the code resides in a ** separate file ** from the html 

2. Type random letters into the Inspector Console

3. Within a few seconds, the keyboard focus moves away from the Inspector Console Window and therefore typed characters are ignored.  Now press [enter] -- the keyboard focus is now in the Inspector Code Window and whatever is typed will end up modifying the javascript code!

What is the expected behavior?
Text inputted into the console should stay in console

What went wrong?
Text went into code window.

Did this work before? No

This is frustrating when I'm debugging and trying to use the console to view objects or variables.  The code gets mucked up and I have to reload and start over.
