Support Views 'Global: Combine fields filter'

Summary

The Views filter 'Global: Combined fields filter' allows for a search to be performed on several fields at once in Views.

However when an entity reference field is used (even as the sole field) the ID of the referenced entity that is searched on, regardless of the field formatter selected for the field. ie: you cannot search for the 'label' of the referenced entity.

Steps to recreate the current situation

Ensure at least one content type has an entity reference field, and ensure there is content present.

Create a view that lists several pieces of content, including the entity reference field - with the formatter set to 'label'.

Add the 'Global: Combine fields filter' to the View
- Expose the filter
- Choose the entity reference field as the one field to 'combine'

Test the filter
- Search for the label of the entity reference field - no results
- Search for the node ID of the referenced entity - the result is displayed
