Re: [svgwg] Character counting in text 'x', 'y', 'dx', 'dy', and 'rotate' attributes.

I also added a test for cursive arabic at https://w3c.github.io/i18n-tests/quick-tests/svg-counting/svg-counting-002. I didn't apply any direction to the string.

All browsers split each letter, but Firefox & Edge retained the joining forms of the glyphs. Chrome and Safari used isolated glyph forms.  FF/Edge cascaded RTL; Chrome/Safari, LTR.

Firefox/Edge
