DataStateChangeEventArgs.search have declared wrong type Completed

using "@syncfusion/ej2-angular-grids": "^20.1.48"

DataStateChangeEventArgs.search have declared type PredicateModel[]; but at runtime, it actually is SearchSettingsModel[].

as declared (grid-model.d.ts)

/** Custom data service event types */

export interface DataStateChangeEventArgs {

    // (...)

    /** Defines the search criteria */

    search?: PredicateModel[];

    // (...)

}

but at runtime 

it looks like SearchSettingsModel[] 

(grid-model.d.ts) and not PredicateModel[]
