AllowCustom: characters are lost during fast typing

When the option "AllowCustom" is enabled for a TelerikComboBox and the user types something above a certain speed, typed characters are lost. 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.

Is there a way to have the TelerikComboBox behave normally, as it apparently did in versions prior to 4.3.0? We noticed this behavior only some time after upgrading from version 4.0.1, where everything still works properly.

Entering text quickly in the input field leads to the text blinking and becoming partially cleared.

Setting DebounceDelay=0 doesn't solve the problem for me, though it does happen less frequently.

Hello, Anna,

I am sorry to hear that this issue is affecting your application. 

As of now, it is hard to give a concrete date for this bug fix, but there is a straightforward workaround in the meantime. 

The ComboBox has a DebounceDelay parameter which specifies the time between the last typed symbol and the updating of the Value. The default value of the parameter is 150ms. Setting DebounceDelay to zero will cause the Value to update immediately and prevent the characters from being lost during fast typing.

Regards,
Georgi

We already pointed out this problem in May of this year. On the one hand, it is understandable that the prioritization of implementations is based on votes. On the other hand, this is a very fundamental problem, which makes the component almost unusable when "AllowCustom" is activated. We are planning to release an application towards the end of the year where this component plays a very crucial role. Therefore I would like to ask again with emphasis to fix this problem in one of the next releases!
