Re: [csswg-drafts] [css-fonts] Add new CSS properties math-script-level and math-style (#3746)

<TabAtkins> dbaron: I think one of the reasons for this is that mathml has attributes that specify both the ratio of font-size for each change in script level, and the min font-size at which you stop changing it.
<TabAtkins> fantasai: Does this mean we're adding font-min-size back?

The MathML Refresh CG had decided to remove the MathML scriptminsize and scriptmultiplier attributes, that's why these are not included in the proposal (we still need to remove them from Gecko). The former is better configured elsewhere (outside of the MathML world) while for the latter we rely on the factors specified in the OpenType MATH table.

The MathML Refresh CG had a11y concerns regarding the font size, because it can scale down very fast in very nested math expressions. Hence we need a minimum limit to keep the text readable. @emilio had suggested to rely on the font-min-size property for that purpose. However, It's fine if you remove it, as long as browsers have some global configuration to set a minimum value for the used font-size.

I removed the comment regarding font-min-size and font-max-size from the proposal, since that's no longer a concern.
