When targeting WP 8.1, if you specify custom font which is included as Content in the project, the calculated height of the Button is incorrect (41 pixels). Since the height is set explicitly by Xamarin.Forms it seems that it doesn't take into account that the font loads asynchronously and doesn't update the
height when the font loads. Entry exhibits the same behavior.
Also, if I create a button with the custom font in the main page of the WinPhone project and then put LoadApplication(new MobileListViewApp.App()) in its click handler, the heights are correct.
Currently I haven't found a workaround for this (will use one if you point it out until you fix it), but this is preventing me to go further with my project.
This works correctly when targeting WP 8.0 (the default).
I really need a workaround/fix for this!
