I would probably refer to these as "cursor elements" rather than "SVG cursor elements" even more consistently in the code. Names like m_cursorElements and updateCursorElement would be nicer than m_svgCursorElements and updateSVGCursorElement. Type would still make it clear itâs specific to SVG.

I would use a reference:
auto& svgCursorElement = downcast<SVGCursorElement>(*element);
> Source/WebCore/css/CSSCursorImageValue.cpp:110
> + SVGLengthContext lengthContext(0);
Should be nullptr rather than 0.
> Source/WebCore/css/CSSCursorImageValue.cpp:112
> + float x = roundf(cursorElement.x().value(lengthContext));
I suggest using std::round instead of roundf. Also not sure if rounding is correct. Also wondering if we should clamp to the size of the image.
> Source/WebCore/css/CSSCursorImageValue.cpp:115
> + float y = roundf(cursorElement.y().value(lengthContext));
Ditto.
> Source/WebCore/css/CSSCursorImageValue.h:-78
> + HashSet<SVGCursorElement*> m_svgCursorElements;
>
> - HashSet<SVGElement*> m_referencedElements;
Thereâs a stray blank line here. I suggest removing it.
