When recording animation in the Animation Window, only the first rotation gets keyed... all other rotations at another time do not get keyed.

repro:
-create a cube
-create a clip in the AW
-Rotate the cube in the scene view to create a first key
-move the timeline
-Rotate the cube in the scene view to create a second key... cube rotates, but no key is created even if the AW is in rec/auto-key mode.

this is a regression, but bug was also backported to 5.3
this means that this bug is now repro in both...
