composedPath is incorrect for composed bubbling events originating from HTMLAnchorElement

[romansp]

Describe the bug
There's an issue where Event.composedPath will be constructed incorrectly if event.target is HTMLAnchorElement with href attribute being set.

To Reproduce
Steps to reproduce the behavior:

1. Create an element with href attribute set to a valid domain, e.g. https://example.com and it attach to body.
2. Add event listener for created element, e.g. click.
3. Trigger click event on this element. Event should have both bubbles and composed set to true.
4. Inspect value of event.composedPath() inside click event handler.

Expected behavior
Composed path should be the following array: [HTMLAnchorElement, document.body, document.documentElement, document, window].

Additional context
Looks like composedPath checks eventTarget.host to detect IShadowRoot boundary. Unfortunately HTMLAnchorElement also has host property which breaks while loop through parent nodes of the event target.

	if (this.bubbles) {
	if (this.composed && (<IShadowRoot>eventTarget).host) {
	eventTarget = (<IShadowRoot>eventTarget).host;
	} else if ((<INode>(<unknown>this.target)).ownerDocument === eventTarget) {
	eventTarget = (<INode>(<unknown>this.target)).ownerDocument.defaultView;
	} else {
	eventTarget = (<INode>(<unknown>eventTarget)).parentNode || null;
	}
