I would have renamed this to documentLoader.

Should this use dl instead of m_documentLoader? (Maybe there's a chance that
m_documentLoader is replaced mid-function?)

> Source/WebCore/loader/HistoryController.cpp:417
> +    const URL& historyURL = m_frame.loader().documentLoader() ?
m_frame.loader().documentLoader()->urlForHistory() : URL { };

I'd change this to no longer hold a const reference, since urlForHistory()
returns a const&, it will always be copied anyway AFAICT.
