Applying a shear on a key press takes focus off the node if the node is rotated

I have an Arc that I am filling with a particular color. Now I am rotating the Arc by 'x' degrees by pressing Key-2. Now I am applying a shear on the rotated arc by pressing Key-4. The Arc is sheared but it stops responding to keyboard inputs after that. This does not happen when the Arc is not rotated prior to Shear. This does not happen on Mobile.

To reproduce the bug, Run the attached test and do the following -
1. Press Key-1 to choose appropriate fill Color.
2. Press Key-2 couple of times to rotate the Arc.
3. Press Key-4 a few times. If the arc stops shearing after the first press, bug is reproduced.

I reproduced it on WinXP-SP3 - jdk6u10 - JavaFX SDK b1.0
