Trace Downstream doesn't return ending barrier

I have a trace network with edges (NHDFlowline) and junctions (WRProxyMZ) that has been validated.  When I trace downstream from a point along an edge (green circle in figures below), using all WRProxyMZ points as barriers, with Include Barrier Features checked, the barrier that stops the trace is not returned in the results.  It seems like it should be returned if Include Barrier Features is checked.

See the two screenshots below. The first shows the map layers and starting flag which I set interactively.  The second shows the Trace tool inputs (no advanced options set) and the resulting map selection after running the trace.

Example data and Pro project are attached.
