> there's no way for it to tell the button to cancel the color change

No, but what should happen in cases like that is that the on-click handler disables the button while it is unresponsive. This will communicate the fact that the button is unresponsive visually to the user and also inhibit the button-was-pressed feedback.

Of course, one can fix these problems. GP was merely saying why this kind of mistake is common; it is definitely a mistake, not an inevitability.
