/**

|
* The `$doingMerge` parameter of the `$group` stage is intended to be an internal parameter. Since
|
|
* we cannot reliably enforce its internal status when authorization is disabled, it is necessary to
|
|
* ensure that the accumulator functions behave correctly, even when used within a $group stage with
|
|
* $doingMerge: true.
|
|
* This suits tests array accumulator functions which were enabled for $group
|
|
* in 8.1. TODO SERVER-97514: Once featureFlagArrayAccumulators is removed the tests can be moved to
|
|
* the main file: group_doing_merge.js.
|
|
*

|
* @tags: [
|
|
* requires_fcv_81,
|
|
* featureFlagArrayAccumulators,
