Steps to reproduce the problem:
1. Set org.gnome.desktop.interface text-scaling-factor to any value.

What is the expected behavior?
Chromium will render fonts at the specified scale factor, but the UI elements (window chrome, etc.) will remain the same.

What went wrong?
Chromium scales up the entire UI to the specified text-scaling-factor.  It should only use the value of the "scaling-factor" key instead, not "text-scaling-factor".  These are distinct and have different uses.  "scaling-factor" is used to enable hidpi mode in GNOME.

Did this work before? N/A 

Chrome version: 57.0.2987.98  Channel: n/a
OS Version: 4.10.0-19
Flash Version: 

Use case:
text-scaling-factor is required to make sure that fonts are rendered correctly (72 DPI = 2.54 cm high on my particular display).  This is because many desktops such as GNOME reset the system DPI to 96, regardless of the actual value, and just making everything a headache for everyone in general.
