Bug report

When MultiSelect is used inside Grid columns filter, it is closing immediately after clicked in the MultiSelect filter input.

Reproduction of the problem

1. Open the Knowledge Base article - https://docs.telerik.com/kendo-ui/knowledge-base/multiselect-used-for-column-filtering
2. Click on the 'Name' column filter icon to open the filter popup.
3. Click in the MultiSelect input filter.

Current behavior

The filter popup is closing first time when clicked. Next time when the filter popup is opened it is not rendered properly.

Expected/desired behavior

The filter popup should not be closed when clicking in the Multiselect filter input. The MultiSelect list items should be rendered below the filter input.

The issue is a regression introduced in 2022.1.301 with the following commit telerik/kendo@bb73744
