The class UserOperationLogManager that creates and submits user operation log entries, explicitly checks for history level full before creating a log entry. This should use the method HistoryLevel#isHistoryEventProduced instead or else custom history levels can never be configured to receive user operation log entries.

Side note: check all usages of #isHistoryLevelFullEnabled, e.g. the usage in UserOperationLogManager#deleteOperationLogEntryById also does not look right.
