Classic column menu filter container has incorrect "overflow" property

[kendo-bot]

Bug report

When opening the filter menu of a specified column through the classic ColumnMenu, the filter container is displayed with scrollbars when the dropdown of the filter operator is opened.

Reproduction of the problem

1. Define a Grid and enable its classic ColumnMenu.

2. Open the filter menu of a specified column and then open the dropdown to select a filter operator.

3. The filter container has scrollbars. The "k-menu-popup" element has "overflow: auto";

Use the following demo to test the case and select the "classic" type for the ColumnMenu: https://demos.telerik.com/kendo-ui/grid/column-menu

The issue can be also observed in a scenario where there is a date column and the user tries to open the calendar for filtering in the column menu - https://dojo.telerik.com/zoDUibfV

The issue does not appear when using version 2024.4.1112.

Expected/desired behavior

The filter menu container must not change its appearance when the dropdown opens.

Workaround:

<style>
.k-menu-popup {
    overflow: visible !important;
}
</style>
