Comments are not persistent?

[akadoya]

livestatus API is not exposing the persistent comments after reloading/restarting arbiter although the shinken UI shows the comments/downtimes.
Is this expected behavior for simple-log? if so, which backend would work to keep the persistent data for comments and downtimes?
