[csswg-drafts] [css-inline-3] Should dominant-baseline support the legacy SVG text-before-edge and text-after-edge values? (#13485)

kbhomes has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-inline-3] Should dominant-baseline support the legacy SVG text-before-edge and text-after-edge values? ==
The [`dominant-baseline`](https://drafts.csswg.org/css-inline-3/#dominant-baseline-property) property is specified to support `text-top` and `text-bottom`. It does not currently allow for `text-before-edge` and `text-after-edge`, which were allowed values in [SVG 1.1](https://www.w3.org/TR/SVG11/text.html#DominantBaselineProperty), are supported today for SVG text by Firefox and Chrome, and which I don't see listed in [SVG 2](https://www.w3.org/TR/SVG2/text.html#DominantBaselineProperty) as being removed (unlike other values like `use-script`).

Meanwhile, [`alignment-baseline`](https://drafts.csswg.org/css-inline-3/#alignment-baseline-property) _does_ have a section about allowing the legacy SVG `text-before-edge` / `text-after-edge` values and mapping them to `text-top` / `text-bottom`. This legacy mapping is also mentioned in [SVG 2](https://www.w3.org/TR/SVG2/text.html#AlignmentBaselineProperty).

So I'm wondering if `dominant-baseline` should allow the same legacy `text-before-edge` / `text-after-edge` values as `alignment-baseline`, or if these were intentionally removed.
