[csswg-drafts] [css-inline] CSS properties appply to SVG elements (#3411)

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

== [css-inline] CSS properties appply to SVG elements ==
Some of the properties in CSS inline apply to certain SVG elements as well. According to SVG2:
* `alignment-baseline` to `tspan` and `textPath` elements
* `baseline-shift` to `tspan` and `textPath` elements
* `dominent-baseline` to [text content elements](https://svgwg.org/svg2-draft/text.html#TermTextContentElement)
* `inline-sizing` to `text` elements (at-risk for SVG 2)
* `line-height`  to [text content elements](https://svgwg.org/svg2-draft/text.html#TermTextContentElement) (SVG2 actually misses to specify it) CC @AmeliaBR 

Those are the properties currently covered by SVG's text algorithms. Some of the other properties in CSS inline layout should apply to certain SVG elements as well in the future.
