"""Wrapper script for running WebXR Android browser tests on an emulator.

The WebXR tests require specific arguments when run on an Android emulator,
such as using the validating command decoder to avoid host OpenGL ES
driver translation stalls.

This script wraps the `android_browsertests` test runner and appends the
necessary flags by default.
