Re: [svgwg] Specify which attributes/properties are horizontal vs vertical vs other

I discovered a case of broken interop caused by the lack of clarity about how percentages are resolved: the `textLength` attribute.

Safari, Edge and Firefox treat this as an other/diagonal length.  (Although Safari has an unrelated bug where they add extra space after the last character.)

However, Chrome always resolves against width (even for vertical writing mode).

[Test case](https://codepen.io/AmeliaBR/pen/4cab473d71302f0f2b238e3dee1f5b1d/)

Probably fair to call this a Chrome bug, but it isn't explicitly defined in the spec, either.
