Example URL:
https://mobile.twitter.com/todd

Steps to reproduce the problem:
1. Go Chrome > Preferences > Advanced > Web Content > Font size  
2. Set the font size to Large
3. Visit a website with fonts defined in px (e.g. https://mobile.twitter.com/todd)
4. Notice the font sizes are not scaled up

What is the expected behavior?
I would have expected Chrome to honor my preference for a larger/smaller font size regardless of the units used to define the font size. This expectation was informed by how both Safari and Firefox allow me to set font size independent of page zoom and in both browsers my font size pref will be honored regardless of the units used to define the font size.

For additional context, I was reading this post on using px vs rem (https://benfrain.com/just-use-pixels/) and the author points out that if you just adjust text size in chrome prefs "it won’t have any effect on text content specified with pixels." Considering the importance of honoring a user's font size prefs for accessibility, I thought it was a least bringing this to the Chrome team's attention.

What went wrong?
The font size is not adjusted when the font size is defined in px
