Re: [svgwg] refX/refY keyword forms unimplemented and no WPT tests (#1137)

Additional Insights: 0 implementation of refX` / `refY` for the symbol element.

- **WebKit** `Source/WebCore/svg/SVGSymbolElement.cpp` — zero
  references to `refX` / `refY`. The class only registers
  `SVGFitToViewBox`. Compare `SVGMarkerElement.cpp:51-90` which
  registers and parses both attributes.
- **Blink**
  `third_party/blink/renderer/core/svg/svg_symbol_element.{h,cc,idl}`
  — zero references. Compare `svg_marker_element.cc:53,106,172`
  which references `kRefXAttr` / `kRefYAttr`.
- **Gecko** `dom/svg/SVGSymbolElement.{h,cpp}` — zero references.
  Compare `dom/svg/SVGMarkerElement.cpp:32,34,75,79,201` which
  registers and resolves both attributes.
