Steps to reproduce the problem:
1. Get a Macbook Pro w/ retina display 
2. Plug in an external display to do multi screen (4k screen)
3. Open Incogneto to ensure plugins not causing issue
4. Open Dev tools and open Device Toolbar (cmd+shft+m)

What is the expected behavior?
The web app I'm viewing should display correctly (100% inside of mobile container) on either screens

What went wrong?
On retina screen everythings fine, but when I drag that screen to my 4k display it gets shrunk inside of the display (see attached image)

Did this work before? Yes unknown (about 1 month)
