i was wondering, why is Ext.fx.layout.Card forced to type = "scroll" on ChromeMobile?

I removed the following condition in Ext.fx.layout.Card`s Constructor (ST 2.1)
else if (type === 'slide' && Ext.browser.is.ChromeMobile) {
    type = 'scroll';
and there seems to be no issue with ChromeMobile on my Samsung Galaxy S2 (Android 4.0.4, latest Chrome from Google Play).

It would be nice to use animations on Chrome, especially for the NavigationView which uses Card Layout and Card FX by default.
