Kendo-angular: Kendo Grid clear filter button modifies input filter

[montella1507]

All inputs should be considered immutable due to one-directional dataflow. It is common practice and it works correctly in most situations, for example - if you add filter via filter row, @Input filter / filters are not modified - changes are pushed via @Output() filterChanges etc.

However - clear of the filters via Kendo grid "clear button"

DOES change property Filters of @Input filter (CompositeFilterDescriptor) .

This is Input mutation and this violates uni-directional dataflow and it will crash with things like ngrx with strict immutability.

Expected behavior
None part of grid should mutate inputs.

Version:
version "3.14.1"

I have a similar problem when using kendo-grid-string-filter-cell.

<ng-template
    kendoGridFilterCellTemplate
    let-filter
    let-column="column"
>
    <kendo-grid-string-filter-cell
        [showOperators]="showOperators"
        [column]="column"
        [filter]="filter"
    >
    </kendo-grid-string-filter-cell>
</ng-template>

@Input filter, which comes from "let-filter", is changed by this:
