### 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]
The server filtering is not working for MultiColumnComboBox defined using a tag helper.
Reason: The initialization script returns:
..... kendo.ui.ComboBox.requestData(.....
instead of
..... kendo.ui.MultiColumnComboBox.requestData(.....
For reproduction details please refer to ticket: #1435798
The server filtering is not working and the server returns all items from the DataSource.
The server should filter the response based on the data coming from the view.
