What steps will reproduce the problem?

1. Add an onKeyUp listener to a contenteditable span or div element
2. Listen for modifier state with getModifierState()
3. Click on a keyboard key and shift
4. Release shift before releasing the other keyboard key

What is the expected output? What do you see instead?
getModifierState() should detect the type of modifier used. But, it does not.

What version of the product are you using? On what operating system?
Dart Editor version 1.0.0_r30798 (STABLE)
Dart SDK version 1.0.0.10_r30798

Ubuntu 13.10 64
