Element: setHTML() method

Cursor build a pseudo-sethtml: https://github.com/skorotkiewicz/pseudo-sethtml

This code only does the most basic and naive regex filtering that even a beginner XSS course's inputs would work against. With the Node example code and input string:

  <p>Hello <scr<script>ipt>alert(1)</scr<script>ipt> World</p>

The program outputs:

  $ node .
  <p>Hello <script>alert(1)</script> World</p>
  {
    sanitizedHTML: '<p>Hello <script>alert(1)</script> World</p>',
    wasModified: true,
    removedElements: [],
    removedAttributes: []
  }

Asking a chatbot to make a security function and then posting it for others to use without even reviewing it is not only disrespectful, but dangerous and grossly negligent. Please take this down.

I wonder why Cursor chose regex approach when it is widely known that it is a wrong method. Is it a result of training on low-quality forums for beginners?
