What is the expected behavior?
SVG/text should be displayed the same as HTML/span.

What went wrong?
When contents of SVG <text> includes Variation Selector and its letter-spacing is not "normal", the Variation Selector is ignored. Normal glyph (not a variation) is shown.
And letter-spacing is wrong.
For IVS, small spacing becomes smaller, large spacing becomes larger.
For SVS, it seems spacing is doubled.
