Plugin configuration is permanently lost upon intermittent plugin load failure
If a panel plugin load fails, the plugin configuration is lost, dropped or corrupted. That's especially bad, if the load failure is only intermittent.
For the origin of this issue, please see this sub thread: #151 (comment 66646)
Expected behavior: The plugin configuration shall always be preserved. It shall only be deleted upon user request. If a any fatal error is detected during panel startup, it shall not write to the configuration.
