-----------------------------------------
[~ivandasch], [~ivan.glukos],
I reviewed the ticket, change looks good to me, tests are provided (executed
them locally with/without functional change: they pass and fail as expected).
I restarted TC build as it had a timeout in Basic1 suite. If it passes with
acceptable overall status, we'll be good to proceed with merging.
