EFL is a false negative - it looks like the compiler was killed.

[Myles C. Maxfield]

Style is also a false negative - the style checker doesn't understand single line functions.

Shouldn't this be:
WeakPtr(Ref<WeakReference<T>>&& ref) : m_ref(WTF::move(ref)) { }

I don't think so. I'm trying to copy the Ref that the caller uses when calling this function.

Then you should use copyRef() at the call site.
