I´m trying to style sencha and when i include all the default sencha styles everything works fine, but when using a prompt message box i cant see the input field, why is this?

To test this, i just put a: Ext.Msg.prompt("test") on the onReady event of Ext.setup, then using this scss:

@import 'sencha-touch/default/all';
@include sencha-panel;
@include sencha-buttons;
@include sencha-sheet;
@include sencha-picker;
@include sencha-toolbar-forms;
@include sencha-tabs;
@include sencha-toolbar;
@include sencha-carousel;
@include sencha-indexbar;
@include sencha-list;
@include sencha-layout;
@include sencha-form;
@include sencha-sheet;

The prompt dosent have an input field! _????
