[Bug][MultiSelect, Form] Error is thrown when a value is entered in the input of the component

[PekoPPT]

Describe the bug
The MultiSelect component throws a console error when a text value is entered in its input and the component is used as a part of the Native Form.

The issue is replicable only when a text is entered in the component's input. Everything works as expected if a value is selected from the MultiSelect's popup list.

• A possible workaround for the bug is demonstrated in this StackBlitz project.

To Reproduce

1. Open this StackBlitz example
2. Enter random text in the MultiSelect's input
3. Open the browser's console and see the following error

Expected behavior
No errors should appear in the browser's console when using the MultiSelect component as a part of the Form component, no matter the specific configuration of the MultiSelect.
