### Bug report
When the Kendo UI DateTimePicker widget with componentType set to 'modern' is used in the filter menu of the Kendo UI Grid and the "Set" button is clicked, the form is submitted automatically.
### Reproduction of the problem
1) Set filterable.ui to be a DateTimePicker with componentType: modern;
2) Open the filter menu. Choose a date from the picker and click "Set";
3) The form is automatically closed/submitted.
A Dojo sample for reproduction (the 3rd column of the grid): https://dojo.telerik.com/ANEFExOC
### Expected/desired behavior
The form should not be automatically closed/submitted.
### Environment
* **Kendo UI version:** 2021.1.119
