Category: MultiColumnComboBox
Type: Bug Report
Entering text quickly in the input field leads to the text blinking and becoming partially cleared.

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.

Our application also suffers from this issue! Dear Telerik, when can we expect a fix?

We encountered this problem as well recently using the "TelerikComboBox" component. Here is a GIF showing the problem on the page https://demos.telerik.com/blazor-ui/combobox/custom-values – I typed "123456", but end up with "1246" instead. In between the input field is showing some weird glitching.

I am surprised to learn though, that this problem is known for two months now and nothing has happened, this ticked is still "Unplanned".

I compared the source code of `TelerikComboBox` for version 4.0.1 and 4.3.0 and found no differences there, that would explain the changed behavior. There are changes in the base component "ComboBoxBase", however, namely the introduction of a "private bool _shouldUpdateJsValue". This component is also the base component for "TelerikMultiColumnComboBox", so to me it is quite certain that these changes are causing the problem.

Could you please have a look at this problem and prioritize finding and implementing a solution? Thanks!
