FYI, Gecko does not support the old keyword values in our new Writing
Modes implementation.

Thank you for the info, I misunderstood when we discussed about inheriting writing-mode from HTML to SVG.

I wrote a simple test how Gecko handles this[1] and figured out that I was wrong:

1. Gecko supports "vertical-rl" both in HTML and SVG and inherits
2. Gecko no longer supports "tb*" in either HTML nor SVG

It was a bit of surprising to me that Gecko does not recognize "tb" in SVG. Is this intentional? I can't find "vertical-rl" in SVG 1.1 nor 2.0. Is it in 3.0 draft?

writing-mode (as many other CSS properties) was first defined in a SVG spec and will now be described by a CSS module under the supervision of the CSS WG. (In this case the CSS WG is also the author of the spec.)

You won’t find a description of writing-mode in SVG 2 or any other future version of SVG. Instead SVG will reference the CSS module directly.
