Resizing Renderer (on orientation change) corrupts window.innerWidth/Height

Description of the problem

I may have discovered a very strange bug:

If you adjust the three.js (full-screen) canvas size by calling renderer.setSize(window.innerWidth, window.innerHeight) on resize, switching from landscape to portrait mode messes up window.innerWidth/Height.

Yup, it actually seems to change what window.innerWidth/Height returns.

I have set up a small test case inside this repository.

1. Open test.html
2. Fire up Devtools
3. Toggle Device Toolbar
4. Select a phone
5. Switch from landscape to portrait mode and observe console output

This bug also occurs on my android phone with Chrome. It messes up a project real bad I am currently working on and I was able to get rid of the bug by excluding the line renderer.setSize(window.innerWidth, window.innerHeight).

I can add additional information and do further testing if this is not intended behaviour and I didn’t make a mistake.
