### Bug report

When the Virtualization of the MultiColumnComboBox is enabled, the table headers and rows are not aligned correctly.

### Reproduction of the problem

A Dojo sample for reproduction: https://dojo.telerik.com/ORalaWoq

The tables and rows are aligned as expected when using version 2021 R3 SP2 (2021.3.1207).

A temporary workaround:

<style>
    .k-table-list .k-table-group-row, .k-table-list .k-table-row {
        display: inline-flex;
    }
</style>

### Expected/desired behavior

The headers and rows should be aligned correctly when the Virtualization is enabled.

### Environment

* **Kendo UI version: 2022.1.412
* **jQuery version: 1.12.4
* **Browser: [all]

Add an option to turn off the auto selection of a matching record after typing in the component's input area and then clicking away.

Currently, the component automatically selects the respective item with text matching the input. For example: https://demos.telerik.com/aspnet-core/combobox/serverfiltering

1. Type in Chang in the input area and then click away.
2. After clicking away, the text Chang remains in the input and if you reopen the list, the ComboBox shows the item with text Chang as selected.
