[GraphHopper] Incomplete routeing (@ Gates?)

Using the GraphHopper.com/maps example implementation or an existing Routeing application that uses the GraphHopper API I frequently come across broken routes.
This appears to (almost certainly, almost always), occur at gates ~ whether the routeing is walking, cycling or driving.
This should be a usable example of walking routeing, where there is a valid path between start and end, but because of the gate it goes a different route to the 'nearest point' on the far side of an impassible barrier.

While I can continue working with the RwGPS application with this fault, as gates are fairly infrequent for cycle planning, and not *very* common on footpaths, it does require some fiddle to make it work (identify a failed routeing, switch map styles to show gates, follow route to immediately before the gate, 'draw line' to connect across the barrier, follow route from immediately after the gate... ok for one or two, or if you are familiar enough to know where the routeing will fail... not so much "fun" for longer routes on FP, in novel terrain.
