Shortcut stops working on the iframe side after code reload

[wilkerlucio]

When the page reloads the iframe seems to get re-mounted, when that happens the keyboard event listener is lost and for some reason (debug needed) it can't attach the event back. This doesn't prevent the shortcut to work on the main frame, clicking there and hitting the shortcut works, but it's a little annoyance that you have to click out before the keystroke works.
