Rebuilding docker executes last (already executed) CRON triggers: Bug?

I’ve noticed this in my workflows for the past few weeks, that whenever i rebuild (stop > rm > up -d) my docker containers, some of the workflows with CRON triggers, which have already executed within the past hour or so, get executed again.

Is this a bug?
Or, am i supposed to rebuild the docker containers in some different way, to avoid this?
