Command (Apple key ) + V, C, X, (ArrowKeys) combinations do not work in MaskedInput for Silverlight under MAC. They should work just like when Control is pressed instead of Command. For example string '1.23' is pasted in RadMaskedNumericInput and Text becomes 1.23.456 which cannot be parsed to value, and also, Value is not updated at all after Command + V paste operation. Expected: Text and Value should become 1.23 in scenarios when mask is not empty.
