StatusBar.currentHeight should be dynamic on orientation change

[bryankang]

On android devices, StatusBar.currentHeight returns the value of the status bar height for the orientation that the app was opened.

For devices like the Pixel 3 XL, it has two different status bar heights depending on orientation. The portrait uses a notch, so it's taller than the landscape counterpart.

When you launch the app on landscape, StatusBar.currentHeight returns 28. Launching it on portrait returns 40 something. Since these values are static, rotating the device results in the wrong status bar height for that orientation.
