Re: [csswg-drafts] [css-fonts] font-size: 'medium' value is the user's preferred font size

It still comes down to this, as @AmeliaBR said:

> For me, the first question is: do browser's implement it this way? That is, do they adjust the actual value of font-size: medium text to match the user's preferred setting, or do they match it to an absolute value?

Whether browsers offer an option to adjust preferred font size (they do) and whether this is an accessibility benefit (it is)  and the precise UI employed and how this scale or zoom is presented to the user, is not the issue here. The issue is, having changed the size, _does the browser update_ what `medium` (and all the other keywords) mean?

Testing with Amelia's pen in Firefox (60.0b15) Chrome (Canary 68.0.3406.0) and Edge (EdgeHTML 17.17134) all three sizes (100%, medium, 16px) were the same, and all scaled together when zooming. Text can be made as large as you like, and everything scales together. So the low vision accessibility requirement is met, and also is more robust in the real world regardless of how the font size was set; the design scales fluidly.
