Number syntax: digit-sequence "."

[dirkschulze]

SVG Path data as well as SVG transforms and probably other SVG specific attributes that take numbers allow: 1..

It seems only Edge does support this:

Should this be removed? Do we just need more tests?

Note: CSS numbers do not support this syntax either.

https://www.w3.org/TR/SVG/coords.html#TransformAttribute (replaced by CSS Transforms but sill relevant since the number syntax should be defined the same for all appearances. w3c/csswg-drafts#2623 (comment))

Adobe Illustrator does support this syntax as well.

@dstorey @AmeliaBR @longsonr could you chime in please and say what you think about this?

As an interesting note: The x, y, width and height attributes do support the digit-sequence "." syntax in Safari, Chrome and Edge but not in Firefox.

This is a duplicate of #331.

Could you add your comments there, Dirk?

@AmeliaBR Thanks. I did create and added a summary there.

Number parsing should be consistent with CSS rules. I highly doubt Firefox will change unless the CSS spec changes.

@longsonr as @AmeliaBR said, comment on #331 please.
