onkeydown Events no longer propagate to parent of TelerikGrid after upgrading Telerik.UI.for.Blazor from 9.0.0 to 12.3.0

Hello,

we recently updated Telerik.UI.for.Blazor from 9.0.0 to 12.3.0, afterwords we noticed that in several instances where we use the `TelerikGrid` component, keyboard interactions stopped working. Specifically the `@onkeydown` seems to no longer propagate to parent elements of the grid. As this was not mentioned in the Breaking changes for the version 10 or 12 releases we assume this to be a bug.

here a simplified example:

            <div style="padding: 0; width: @(ShowSidePanel ? "65%" : "99%")" tabindex="0" @onkeydown="@(OnKeyPress)">
                <TelerikGrid TItem="IncomingInvoiceGridItemViewModel"
                             @ref="GridRef"
                             Class="admin-grid"
                             Height="@OverviewHeight"
                             RowHeight="50"
                             Pageable="false"
                             PageSize="PageSize"
                             FilterMode="@GridFilterMode.FilterMenu"
                             Sortable="true"
                             Resizable="true"
                             Reorderable="true"
                             ShowColumnMenu="true"
                             ScrollMode="@GridScrollMode.Virtual"
                             SelectionMode="@GridSelectionMode.Single"
                             OnStateInit="@OnStateInit_SetStateAsync"
                             OnStateChanged="@OnStateChanged_SaveStateAsync"
                             SelectedItemsChanged="@OnSelectedItemsChanged_LoadPdf"
                             OnRead="@OnRead_UpdateFilteredItems">
                    <GridSettings>
                        <GridColumnMenuSettings Lockable="false" />
                    </GridSettings>
...
<!-- aggregates, columns and noDataTemplate omitted -->
...
                </TelerikGrid>
            </div>

Implementation / usages of the features did not change, only updates where changes required by the update Telerik.UI.for.Blazor from 9.0.0 to 12.3.0.

These were the dependencies updated alongside the update of Telerik.UI.for.Blazor from 9.0.0 to 12.3.0 :

Hello Klaus,

I am surprised that @onkeydown has worked on your side, because it's not supposed to and I can't make it work in old versions either. I always advise customers to use @onkeyup to capture key events inside the Grid.

Normally, our components with keyboard navigation do not propagate keydown events. Otherwise you may end up with scenarios where the keyboard navigation of a child component affects the keyboard navigation of a parent component.
