<?php

            $this->query->limit($value);

		            $this->related->qualifyColumn(
			            $this->related->getPathName()

It seems like $this->related->getPathName() can also be of type Illuminate\Database\Eloquent\Builder; however, parameter $column of Illuminate\Database\Eloquent\Model::qualifyColumn() does only seem to accept string, maybe add an additional type check?
