[ALOY-622] app.tss doesn't apply to baseController

In my app.tss I've declared a basic window styling (barColor etc). Most of my controllers build on a custom baseController that delivers the window instances with some additional buttons I need in all my windows. So the first line of my controller looks like this:

exports.baseController = 'base/window';

$.getView() will return the window from the baseController. The problem is, that the styling of my app.tss isn't applied. The compiled controller for base/window in the Resources folder looks like this:

$.__views.window = Ti.UI.createWindow({
   id: "window"
});

Missing all properties from my app.tss. If I create the window directly without using the baseController, everything is fine, but would result in many lines of duplicated code
