MultiSelectTree filter shows [object Object]

[PindaPixel]

Describe the bug
When closing and re-opening the dropdown filter and an item is selected, something calls the onfilterchange event with an object for its value.

To Reproduce
Steps to reproduce the behavior:

https://www.telerik.com/kendo-vue-ui/components/dropdowns/multiselecttree/filtering/

1. Select an item from the dropdown
2. Close the dropdown
3. Re-open the dropdown
4. Observe the filter field

Expected behavior
Filter should not be altered unexpectedly

Additional context
I've narrowed it down to the focusout and blur event types. Even though I explicitly ignore these events and do not alter my filter state variable, the text in the text input remains.

onFilterchange(event: { filter: FilterDescriptor; event: { event?: { type: string } } })
{
    // in the events where I would not expect filter to change, its type is object
    if (typeof event.filter.value !== "string")
    {
        // Even though I do not set my filter ref, the text input still shows `[object Object]` without actually filtering the items.
        return;
    }

    filter.value = event.filter;
}
