This was my attempt at fixing the crash inside android egl library, didn't work
:(

Yes, this SetWindowSurface() codepath here is not used for WebView. The
difference is that WebView creates EGL window surfaces for the renderer-side
compositor (to render into a SurfaceTexture).

For non-WebView, we add an ANativeWindow to the tracker here which is the actual
window surface for the browser compositor.
