Re: [svgwg] The interpolation of large_arc_flag/sweep_flag of Elliptical Arc in SVG Path

> I think it still needs to be specced since we need to clarify whether the "fall-back to 50% flip" applies to the individual command or to the value as a whole. My understanding is that in the absence of any other text, it would apply to the value as a whole, but we want it to apply to the command here.

Flipping an arc command (i.e. the radius, etc), but not the path as a whole, is non-trivial and not useful as the path will also contain other commands.

In an animation from `M ... A ... 0 0 100 200 L 103 204` to `M ... A ... 1 1 200 100 L 203 104` the line direction and length should be constant.

Flipping only the flag is reasonable, flipping the entire path is reasonable, flipping just the arc command is not.
