Change behavior of FxTextInput so it matches TextInput when text property is bound to a Number variable and that Number variable is bound to the text property. This is needed for FB.
Technically this isn't correct behavior because there are times when the text getter will return a different value than what is displayed in the text field. There was quite a bit of discussion about what to do and we finally decided to match the halo behavior.
QE Notes: add a test case for this scenario
