elementFromPoint is not working

[danieldongit]

Describe the bug
I am using vendor code that utilized the elementFromPoint function (Codemirror 6).

To Reproduce
Reproduction will take setting up codemirror in a development environment along with a testing framework.
Might be a bit of a process

Error Log

TypeError: root.elementFromPoint is not a function
posAtCoords node_modules/@codemirror/view/dist/index.js:3418:24
let doc = view.dom.ownerDocument;
let root = view.root.elementFromPoint ? view.root : doc;
let element = root.elementFromPoint(x, y);

Thank you for reporting @danieldongit! 🙂

As Happy DOM can't render the Elements, it doesn't know which element will be at the point, but it should be possible to add a method that just returns null.

public elementFromPoint(_x: number, _y: number): Element | null {
      return null;
}
