Start server in standalone mode, with clustered configuration:
bin/standalone.sh -c clustered.xml
Change cache or cache container configuration:
e.g. click on cache container -> Configuration -> change settings -> click save/apply changes -> restart required dialog is displayed -> click restart now

Result nothing happens.

Expected result: Dialog saying manual restart is required for this change to take effect, no action buttons offered. This works correctly in standalone mode with non-clustered configuration (started by bin/standalone.sh)
