Text nodes assigned to a linked slot are not clickable

• Component: DOM
• Status: RESOLVED FIXED

[Jan Miksovsky]

See http://jsbin.com/qinaxo/edit?html,output

This shows a link in a Shadow DOM subtree. Half the content is directly inside the anchor element, the other half of the content is assigned via a `<slot>` element.

Expect: The entire link should be clickable.
Actual: The content assigned to the `<slot>` element is not clickable.

It would be more stylish to use ComposedTreeAncestorIterator. The current composedTreeAncestors() starts from the parent though so dealing with the OrSelf part here would require refactoring a bit (or adding new composedTreeLineage() helper that starts from the current node).

I think we should eventually get rid of all these random helpers. On the other hand just switching parentOrShadowHostNode->parentInComposedTree is a good way to make progress fast.

I'd keep parentInComposedTree for now, and we can do this in a separate patch if we'd so wished.
