* Remove Bindable. Fix Observable & ObservableArray tests Fix formattedString text Change implementation of Span, FormattedString & TextBase properties valueChange called before native setter * revetred formattedString tests asserts - formattedText update text property again properties - when getting value we now use always property name instead of key (using key could return undefined for property that is set to its default value) updated fontSize & fontInternal properties on all controls fix font properties so that fontInternal is reset if the new font is the same as Font.default * fix tslint errors
