results of filtering by entity reference view are deleted when adding item to an unrelated field

Problem/Motivation

After adding an item into a multi-value entity reference field A and submitting the form, a value of an entity reference field B generated by a view gets deleted.

Steps to reproduce

1. create a content type with two entity reference feilds
2. specify field A as multi-value
3. make the field B value to come from a view-generated list by choosing Views: Filter by an entity reference view in the Entity selection section
4. select a value from the list in field B
5. specify a value for field A
6. click the Add another item in the field A
7. populate the added field with a value
8. Submit the form

The resulting node is missing value in the field B (or fails to validate upon submission, if value is required in the field)

A possible workaround is to use Simple mode in the Entity selection section instead of the Filter by an entity reference view
