Hi,
As of Fx97 I intend to turn CSS d property on by
default on all platforms, and this also makes SVG path d attribute mapped to d property, so it works as a presentation attribute. It has been developed behind the "layout.css.d-property.enabled" preference.
Status in other browsers is:
1. Blink shipped it already more than 4 years ago
2. Webkit doesn't support it yet.
Bug to turn on by default: Bug 1744599
This feature was previously discussed in this "Intent to prototype" thread: https://groups.google.com/a/mozilla.org/g/dev-platform/c/BTXw4pOfnR4/m/d6xtQXmsBQAJ
Thanks,
Boris
