HTML Web Engine crashes when variable form smart object and mapped variable are shown at the same time

When displaying a variable from a smart object and the mapped variable from the project together, the HTML Web Engine crashes and according to the log, variables do not exist in the runtime. 
Simple project backup attached.

Error text:

zenonV6: bulk advise failed with message: One or more variables do not exist in the runtime...

All mechanisms dealing with variable mapping in Smart Objects are not available in Web Engine nor has Web Engine any information about variable mapping. So this is not a bug but missing functionality. Official decision is not to implement mapped Smart Objects variables into Web Engine for zenon 15 BUT instead try to replace Web Engine with WVS the next versions.
