[5.x]: PHP error when eager loading an element owner that is not the same element type as the nested element

[lukeholder]

What happened?

Description

The following code will cause the error:

{% set addresses = craft.addresses.with(['owner']).all() %}

This is due to

cms/src/base/NestedElementTrait.php

Line 42 in 92440e9

'elementType' => get_class(reset($sourceElements)),

expecting that the element type for the eager loading of the parent is the same element type as the source element.

Adding a matrix field to a category element and using this query can also cause the error:

{% set matrix = craft.entries.with(['owner']).all() %}

Since the category is not an entry element type.

Steps to reproduce

Add this code to a front-end template:

{% set addresses = craft.addresses.with(['owner']).all() %}
