setting the 'default-resource-stickiness' to a positive value now prevents
the restart behavior when a node returns, thanks.
but this is only half of a workaround for the problem below.

this doesn't help if you crash/standby/stop a node.
resources that were running on this node are pushing away
other resources, although both of their scores are equal/unset.
if other free nodes are available the failing resource should start there,
and if none are available shouldn't start at all.

instead heartbeat restarts resources depending on the colocation
constraints, although those should just distribute the resources across all
nodes.

again, all groups shall be treated equal if they have the same score,
the failure of one shall never affect other ones.
IMHO this is a bug.

greetings,
daniel
