On Android Emulator (Small Desktop API 32), EbitenRenderer can be
easily recreated by resizing the window. Thus, EbitenRenderer should
not have any flags like strictContextRestoration. Also, the flag
onceSurfaceCreated_ doesn't work there.
We found that an app freezes for a little while when resuming it.
In order to improve user experience, always use
setPreserveEGLContextOnPause(true) whichever StrictContextRestoration is
true or false.
