Events does not correctly bubble up the DOM tree

[egil]

When an element is clicked using the Click() event dispatch helper, it doesn't cause the event to bubble up the DOM tree like it does in the browser.

[egil]

According to EventDelegator.ts, this is the list of non-bubbling events:

'abort', 'blur', 'change', 'error', 'focus', 'load', 'loadend', 'loadstart', 'mouseenter', 'mouseleave', 'progress', 'reset', 'scroll', 'submit', 'unload', 'DOMNodeInsertedIntoDocument', 'DOMNodeRemovedFromDocument'

plus, if an element has the disabled attribute, these events are also disabled

'click', 'dblclick', 'mousedown',

These test should pass when this is fixed:

public class EventBubblingTest : TestContext
{
	[Fact(DisplayName = "When clicking on an element with an event handler, " +
						"event handlers higher up the DOM tree is also triggered", Skip = "fix with #119")]
	public void Test001()
	{
		var cut = RenderComponent<ClickEventBubbling>();

		cut.Find("span").Click();

		cut.Instance.SpanClickCount.ShouldBe(1);
		cut.Instance.HeaderClickCount.ShouldBe(1);
	}

	[Fact(DisplayName = "When clicking on an element without an event handler attached, " +
						"event handlers higher up the DOM tree is triggered", Skip = "fix with #119")]
	public void Test002()
	{
		var cut = RenderComponent<ClickEventBubbling>();

		cut.Find("button").Click();

		cut.Instance.SpanClickCount.ShouldBe(0);
		cut.Instance.HeaderClickCount.ShouldBe(1);
	}
}
