100% height does not match window height on some devices.

[dcorbin]

Description

The height obtained from useWindowDimensions() and the height provided by "onLayout" when the style is "height: 100%" is not consistent on some Android devices. I have specifically seen this on the Nexus 4 and Nexus 5X devices. When the same code runs on the Pixel 6, it provide consistent results out to many decimal places.

Steps to reproduce

1. Clone this project: HeightBug (github) (based on the standard new tempate-- only App.tsx differs)
2. Run it on a Pixel 6 (emulator, API 33). See that it reports similar numbers
3. Run it on a Nexus 4 (emulator, API 33). See that it does dissimilar numbers (616, and 592 for me).
