According to the issue #5751, the size is not calculating the length properly when we give it a native object with 'length' key, like this:
_.size({ 'a': 1, 'b': 2, 'length': 5 })I excluded native JS objects in size function by
"collection.constructor.name !== 'Object'". Other verification was not needed since the isArrayLike method checked before that we have an array like object.
