Using preloadTabs="true" on <ion-tabs> in Ionic Beta 10 it throws an error

Hello, when using preloadTabs=“true” i get an error:

Uncaught TypeError: Cannot read property 'style' of undefined.

The issue is that the scrollEle from content.js is undefined and it gets called.
Here is the code that is throwing the error:

if (newVal !== this.adjustedTop) {
   scrollEle.style.marginTop = (newVal > 0 ? newVal + 'px' : '');
   this.adjustedTop = newVal;
 }

If i am removing the preloadTabs property the tabs are loading just fine. This was working well in Ionic Beta 9.

This is happening also on the tabs example.

Does anybody have the same problem?
