getCharNumAtPosition work for first glyph only

Method SVGTextElement.getCharNumAtPosition doesn't work correctly when SVGTextElement contains SVGTextPathElement.

Steps to reproduce:
1. Create SVG with textPath element (see tutorial http://tutorials.jenkov.com/svg/textpath-element.html)
2. Call SVGTextElement.getCharNumAtPosition method to get char index by specified x, y position

See online example http://mamchur.net/issues/getCharNumAtPositionIssue/index.html
Just press "Monte Carlo Hit Test" several times & observe issue

Actual Results:

SVGTextElement.getCharNumAtPosition returns -1 and 0 values only

Expected Results:
See https://www.w3.org/TR/SVG/text.html#__svg__SVGTextContentElement__getCharNumAtPosition
