TelerikTimePicker is somehow validated when using inside TelerikCard

[Thomas]

Hi,

I've some TelerikCard components that host different other components but when using lets say the TelerikTimePicker then as soon as you try to input a time via keyboard it gets a red border and seems to invalidate the input.

When using the TelerikTimePicker outside in a simple div then it seems to work.

Also when using the popup to set the time it works. Only keyboard input seems to trigger some sort of validation.
When losing focus the timepicker resets to 00:00:00.

Here's the code of the razor page to replicate the problem:

<TelerikCard Width="20rem">
    <CardHeader>
        <CardTitle>Time Selector</CardTitle>
    </CardHeader>
    <CardBody>
        Startzeitpunkt<br>
        <TelerikTimePicker @bind-Value="@SelectedStartTime" Format="HH:mm:ss" Width="6rem" />
        <br>
        Endzeitpunkt<br>
        <TelerikTimePicker @bind-Value="@SelectedEndTime" Format="HH:mm:ss" Width="6rem" />
        <br>
    </CardBody>
    <CardSeparator></CardSeparator>
    <CardFooter>
        footer
    </CardFooter>
</TelerikCard>

@code {
    protected DateTime SelectedStartTime { get; set; }
    protected DateTime SelectedEndTime { get; set; }
}

I use the latest telerik blazor components 9.1.0 and VS 2022 17.14.9.

Maybe someone has a hint what's wrong with it.

Thomas
