The log says "<processid> has been deleted" when setting statuskey by a environment variable and using a timer delay

This flow:
will give the result " has been deleted" in the log:
Setting the statuskey to the same value, "complete", by a static value instead of a variable:
will not give this problem:
Removing the delay:
will not give this problem either:
Could you please confirm if this is a bug, when it could be fixed and any possible workarounds in the meantime?
