We can't use makeRefPtr & auto here?

Ditto.

Use auto?

Ditto.

It's a bit silly to use a RefPtr here since we're just downcast'ing to another pointer type.
I think it's okay to keep parent & host raw pointers as long as the return type is a RefPtr.

> Source/WebCore/html/HTMLTableRowElement.cpp:59

Again, not certain if it's worth converting these local variables to RefPtr since they're just casted to another pointer type.
