Block visibility with other plugins (term_condition, entity_field_condition) [#3584379]

Problem/Motivation

I've attempted to set up both term_condition and entity_field_condition to control the surfacing of various blocks in my layouts.

When I configure either of these, the block simply doesn't appear. I'm speculating the @Node from URL@ qualifier isn't being exposed to display builder.

Steps to reproduce

Install Display Builder for entity view
Install Entity Field Condition
Enable Display Builder on the Basic Page content type default display mode
Give the Body field a entity field condition, for example, Field: ID, Value Source: Specified, Value to be compared: 1, node: Node from URL
Publish layout
Examine /node/1, observe the body doesn't appear.
