Bug?: Touchkit and BrowserWindowOpnener

Hi guys,

I have an issue with the BrowserWindowOpnener on my iPad Air 2 (iOS 8.1) in Safari:

Opening a new browser window (a new tab) works fine, but when I return there is an additional space below my UI (see screenshots before/after). You can reproduce it in the device simulator.

The same thing works fine in Chrome.

Is it a bug in Touchkit?

Thanks,
Markus
