Bug: transform-origin is not recognized as a valid attribute despite being in SVG specs

[rtpg]

This is re-opening this issue, which is likely too stale to get eyes on it

React version: 18

Steps To Reproduce

1. Go to this JS fiddle
2. Inspect console to see error about transform-origin being invalid

The current behavior

transform-origin is not recognized as a valid attribute

The expected behavior

transform-origin should be recognized as a valid attribute.

From the previous issue, I wrote:

transform-origin is now a proper SVG attribute (seen here), spec references below). I believe this is worth re-opening (and investigating whether there are other missing SVG attributes)

My understanding of the SVG spec reference above is that we should consider this to be valid now.
