Description:

• Create two pages with ActionBarItem that are using IconFonts
• Navigate from pageA to pageB with action-bar set

<ActionItem ios.position="right" (tap)="goBack()"> 
    <Button #backicon text="&#xE87D;" class="material-icons backicon"></Button> 
</ActionItem>

result: Icon is loaded at one place at the initial moment - then the icon is displaced by x (where x is the icon size)
