Exception when resolving links in docstrings of deferred bound methods

[Issue] when resolving links in the docstring of deferred bound methods. For example:

module hello_mod
    implicit none

    private

    type, public, abstract :: foo_t
        contains
        !> See [[bar]] for more information
        procedure(foo_iface), public, deferred :: foo
    end type

    abstract interface
        subroutine foo_iface(self)
            import :: foo_t
            class(foo_t), intent(in) :: self
        end subroutine
    end interface

    public bar

contains

    !> More details about [[foo_t]] API
    subroutine bar
    end subroutine
end module

leads to:

Attribute error
