描述

Document.createElementNS() allows to create a few nonexistent SVG elements. In particular, this function has signatures that allow creating componentTransferFunction, textContent and textPositioning, but these correspond to SVG interfaces which do not have any real element associated.

This can be easily verified by running:

document.createElementNS('http://www.w3.org/2000/svg', 'textContent') instanceof SVGTextElement; // false
document.createElementNS('http://www.w3.org/2000/svg', 'text') instanceof SVGTextElement; // true

(Note that SVGTextElement implements SVGTextContentElement.)

研究方向
The issue is that `Document.createElementNS()` has overloads allowing creation of SVG elements like `componentTransferFunction`, `textContent`, and `textPositioning` that do not exist in SVG. The fix involves removing those incorrect overloads from the TypeScript DOM type definitions. The relevant file is `lib.dom.d.ts` in the TypeScript repository. Look for the `createElementNS` method signatures and verify against the SVG specification which elements are valid. Check existing comments for any additional context or suggestions.
