Draw demo does not work in conjunction with state transfer, sequencer, and flush in the stack. Nodes will join initially and form a cluster. Killing master node puts the survivor in an infinite flush block. The killed node will never join the cluster again.

Bug is not present in version 2.8.0CR6.

Reproduce:

Start two nodes using the command lines below.
Draw on both panels.
Kill master node.
Draw on survivor.
Bring up killed node.
Infinite flush block (regardless of flush timeout).
