Greetings from Syncfusion support.
We have checked with your reported requirement in HeatMap. In order to achieve this scenario, you can set opacity for the Tooltip using the following CSS:
Refer to the code snippet:

<style>
.ejSVGTooltip.e-tooltip svg g path{
opacity:1;
}
</style> |
Please get back to us if you need any further assistance.
