It happened because of the change introduced in commit [1]. Where
mistakenly were used wait_upstream()/wait_downstream() with:

  test_run:wait_*stream(*_id, {status == 'follow'})

with status set using '==' instead of '='. We unable to read status
variable when the strict mode is enabled. It is enabled by default on
Debug builds.

Follows up #5110
Closes #5297
