Dynamic update <style> is not handled by polyfill

[katmai7]

Hi,
I found out that when <style> is dynamically updated with new css, polyfill doesn't handle it.

Example: https://stackblitz.com/edit/js-pkkkut?file=index.js,style.css,index.html,tsconfig.json

After some research I found that the polyfill should parse and apply polyfill logic again after <style> was updated

I've tried to do naive fix and implement update method for StyleElementController:

updated() {
  this.controller?.abort()
  this.connected();
}

But I'm not sure if it a right place to do it.

What is the proper way to make it handle this case?
