@2d9a6032 Most developers don't test reflow with text zoom only. WCAG doesn't require it either (page zoom is sufficient). It's a combination of lack of education and laziness. 

 @7725718e well, true. Can I easily edit text size in devtools? I'm only able to test this by browsing to stuff on my phone right now... 

 @2d9a6032 Firefox allows you to switch between page zoom and text-only zoom. So I use it with text-only zoom for testing text size reflow.
