[Chart] Improve tooltip and crosshair behavior when updating the data of the component

Hi Kendo Theme,

The current behavior will re-render the Chart and the tooltip or crosshair disappear and the user will need again to hover over the series. This behavior can be observed in the following example:

https://stackblitz.com/edit/angular-dmpexe-sf8zoj?file=src%2Fapp%2Fapp.component.ts

The desired behavior would be to keep the popup open or the crosshair present when updating the data.

Thank you for your consideration.

Hello Megan,

We are declining this request due to low interest and demand.

However, if there is a surge in popularity at a later time, we will reconsider its status.

Hiding a series by clicking it in the legend also gets overwritten on update, and it becomes visible again.
