It's possible the problem is actually GTK (which sits between Mutter and
the apps) only supporting integer scales.

Title:
Display scaling 150% causes Firefox and Chrome to return
window.devicePixelRatio = 2
Status in gtk+3.0 package in Ubuntu:
New
Status in mutter package in Ubuntu:
New
Bug description:
## Steps to reproduce
1. Use Ubuntu 20.04 with an Nvidia graphics card with GNOME Desktop.
2. Set display scaling to any fractional value (150%)
3. open up Firefox/Chrome/Chromium. Open up Console and type
`window.devicePixelRatio`
## What happened
I received 2
## What should have happened
I should have gotten 1.5

I reported this bug here instead of in Firefox/Chrome because they
both report the same value only on Linux. They correctly report 1.5 on
Windows, which I believe may be an issue with GNOME.
