Set Empty Values field has no effect on entry relations

[jmauzyk]

Description

We have an entry relations field on Commerce Product elements that is used to add banners to the product page. Our XML data feed provides individual banner titles as subnodes under a Banners element:

<Banners>
    <Banner>Banner Title</Banner>
</Banners>

This works as expected. However, when the Set Empty Values setting is enabled and no banners are associated in the product data feed (as shown below), banner entry relations are not removed.

<Banners>
</Banners>

Steps to reproduce

1. Create a product element with an entry relations field and set a relation.
2. Run a feed import with an empty node for the relations field. Existing relations are not removed.
