Invalid viewport values on Android in portrait mode

[ClementCariou]

Hello, I found a problem with viewport values on the Chrome 92 Android browser in portrait mode.

const regl = require("regl")();
const ctx = regl({});
ctx(({viewportWidth, viewportHeight}) => {
	console.log(viewportWidth / viewportHeight);
	console.log(window.innerWidth / window.innerHeight);
});

Device	Orientation	Viewport ratio	Window ratio
Destop	Landscape	1.9814	1.9814
Desktop responsive mode	Portrait	0.5632	0.5632
Desktop responsive mode	Landscape	1.7739	1.7739
Android Honor 8x	Portrait	⚠️0.7177⚠️	0.5174
Android Honor 8x	Landscape	2.7222	2.7222

1 / 1.7739 = 0.5174 not 0.7177

I didn't investigate the problem further.
