bbb651 3e710465ca HTML: BrowsingContext: Remove m_parent and fix is_ancestor_of ...

`BrowsingContext::m_parent` has been removed from the spec,
and previously `m_parent` was always null.

`BrowsingContext::is_top_level` was already always returning
true before because of that, and the updated spec algorithm
causes assertions to fail.

This fixes the following example:
```html
<a href="about:blank" target="test">a
<iframe name="test">
```
clicking the link twice no longer causes it to open in a new tab.
