[ClusterLabs] Virtual ip resource restarted on node with down network device

I have configured an Active/Passive cluster to host a virtual ip address. To test failovers, I shutdown the device the virtual ip is attached to and expected that it moves to the other node. However, the virtual ip is detected as FAILED, but is then restarted on the same node. I was able to solve this by using a ping resource which we want to do anyway, but I am wondering why the resource is restarted on the node and no failure is detected anymore.
On my setup, this is very easy to reproduce:
1. Start cluster with virtual ip
2. On the node hosting the virtual ip, bring down the network device with ifdown
=> The resource is detected as failed
=> The resource is restarted
=> No failures are dected from now on
