Ensure that selected event is visible

We have an issue that we are not quite sure how to solve. When selecting an event in the list, we pan it into view on the map (when not within the map viewport). This event may still be hidden because it is covered by other events (see image). We need the marker to rise to the top.

I am not sure if VectorGrid will allow us to do this? We might be able to create a separate layer that has only the selected event, and just plots that event on top?? Can we use VectorGrid and plot using SVG and use css to change the z-index???
