The issue is reproducible when the `AllowCustom` parameter is set to `true`.
Typing rapidly in the input field of the MultiColumnComboBox component causes the entered text to blink. Also, some of the inserted symbols are cleared.

Reproduction (if bug)

Open this demo: https://demos.telerik.com/blazor-ui/multicolumncombobox/custom-values

Try to input text rapidly into the input field.

from this screenshot from the demo selecting a value via the keyboard leaves the box blank

to replicate press the down arrow when MultiColumnComboBox has focus

Currently, only the TextField is taken into account when filtering. It would be extremely helpful if other fields besides the TextField could also be included in the filter.

Admin Edit:

This feature request is only for filtering via the component input. For filtering via the column interface and other Grid-like features, please refer to this feature request.
