Tooltip removes Grid filters

Hello,

I'm having issues with two components Grid and Tooltip.
Context: I have a gird and every row inside has a column with button. when you hover tooltip pops up.

However if I add some text to filter grid data, after tooltip appear filters are cleared.

I'm using 2.18.9

code snippet:

<RadzenTooltip />
<RadzenGrid @ref="@ConfirmationLetterGrid" AllowFiltering="true" AllowSorting="true" FilterCaseSensitivity="FilterCaseSensitivity.CaseInsensitive" Responsive="true" Data="@letters" TItem="ConfirmationLetter">
    <Columns>
        <RadzenGridColumn TItem="ConfirmationLetter" Property="Name" Title="Contractor" Sortable="false" />                            
        <RadzenGridColumn TItem="ConfirmationLetter" Title="Approve" TextAlign="TextAlign.Center" Sortable="false">
            <Template Context="ConfirmationLetter">
                <Radzen.Blazor.RadzenButton Icon="attach_email" MouseEnter="@(args => { ShowTooltip(args, new TooltipOptions() { Text = "Re-Send letter", Position = TooltipPosition.Left, Duration = 800 }); })" />
            </Template>
        </RadzenGridColumn>
    </Columns>
</RadzenGrid>

void ShowTooltip(ElementReference elementReference, TooltipOptions options = null) => tooltipService.Open(elementReference, options.Text, options);
