:mrdocs:

Restore the statistics from the specified `savedStatistics` by appropriately combining the current values and the saved values. The behavior is undefined unless `savedStatistics` is a value returned by a previous call to `stashStatictics` on this same object, which has not been passed to `restoreStatistics` yet. This method restores the state of the statistics as if the corresponding `stashStatistics` call has never happened, in the following manner:
