// The amount of time (in milliseconds) between when the bubble closes and when
// pressing on the button again does something. Yes, this is a hackish. I tried
// many different options, all to no avail:
// . Keying off mouse activation: this didn't work as there is no way to know
//   which window receives the activation. Additionally once the mouse
//   activation occurs we have no way to tie the next mouse event to the mouse
//   activation.
// . Watching all events as we dispatch them in the MessageLoop. Mouse
//   activation isn't an observable event though.
// Ideally we could use mouse capture for this, but we can't use mouse capture
// with the bubble because it has other native windows.
