Re: [csswg-drafts] [css-fonts-5] <meta text-scale> limits (#13557)

> &lt;TabAtkins> dgrogan: right now in Chrome in the a11y UI, we allow the user to change the default font size, "medium", to a max of 72px, 600%

My math didn't math. 72/16 = 4.5, not 6. So, we let users change `medium` to a max of 450%, not 600%. The qualitative points still stand though, namely:

(Just recapping what I said on the call)

There are Chrome desktop users _today_ that have changed their `medium` font size from `16px` to `64px` because `64px` makes web text readable for them. (Other users obviously browse at `24px`, `32px`, `48px`, etc).

When these users browse the web, many layouts are broken or at least render differently than what the author expects. But these users empirically, _not hypothetically_, still derive value from browsing the web at their larger sizes.

If we implement this proposal, and a site adds `<meta name="text-scale" content="32px">`, then our `48px`, `56px` and higher..., users can **no longer read** that site. That's the regression.
