instanceof SVGGraphicsElement causes typeError

[MarkLyck]

Describe the bug
I am using happy-dom with vitest and I noticed after upgrading to antd@5.1.2 A bunch of my unit tests are failing with:

this error:

TypeError: Right-hand side of 'instanceof' is not an object
 ❯ _default node_modules/.pnpm/rc-util@5.27.1_biqbaboplfbrettd7655fr4n2y/node_modules/rc-util/lib/Dom/isVisible.js:14:15

At first I thought this was a bug in rc-util a library used by antd. But upon further inspection, it seems like it's a missing feature/case in happy-dom

This is the file that causes the error:

var _default = function _default(element) {
  if (!element) {
    return false;
  }
  if (element instanceof HTMLElement && element.offsetParent) {
    return true;
  }
  if (element instanceof SVGGraphicsElement && element.getBBox) {
    var _element$getBBox = element.getBBox(),
      width = _element$getBBox.width,
      height = _element$getBBox.height;
    if (width || height) {
      return true;
    }
  }
  if (element instanceof HTMLElement && element.getBoundingClientRect) {
    var _element$getBoundingC = element.getBoundingClientRect(),
      _width = _element$getBoundingC.width,
      _height = _element$getBoundingC.height;
    if (_width || _height) {
      return true;
    }
  }
  return false;
};

The part that is causing the error using happy-dom is element instanceof SVGGraphicsElement. If I comment out this if statement all of my unit tests will pass without issues.

To Reproduce
Steps to reproduce the behavior:

1. Create a file that uses instanceof SVGGraphicsElement
2. Run it in a test environment using happy-dom@8.4.3
3. See error

Expected behavior
parsing instanceof SVGGraphicsElement should not cause an error.

Device:

• OS: MacOS
• Browser: node
• Version: "happy-dom": "8.4.3",

Temporary solution
For now I have switched back to use JSdom where this problem does not occur. Will set up happy-dom again once this issue is resolved.
