    Description

      In SERVER-8624, we switched to a mutable argument flag for invoke(). The goal was to make it possible to utilize the function argument directly instead of having to perform a deep copy.

      When manipulating one of these arguments, some properties added to the argument appear in the result set with duplicate field names (when running with jsMode:false).
