Status bar overlapping Toolbar with FormsAppCompatActivity

I updated my app to Forms 1.5.1 and I'm switching over to using AppCompat for material design, but I'm having a problem with the toolbar. Once I get to my main page after signing it, the toolbar is overlapped by the status bar. This is a TabbedPage wrapped in a NavigationPage. After a rotation, the toolbar is drawn correctly, completely below the status bar. Screenshot is attached.

Note: this only seems to happen on Lollipop devices, older devices actually using the support library draw the toolbar correctly the first time.
