- Select and object with an animation
- Go to the Animation window and switch to Curves mode
- Select one keyframe and drag it around (a label with the coordinates of the keyframe shows up)
- Press Escape while dragging

Expected: Keyframe snaps back to original position and label disappears (Unity 4.2.1 behaviour)
Actual: Keyframe snaps back, but label is disaplayed forever. You can't make it disappear
