title: Rendering a marker "on top of everything" (including whatever is rendered in floatPane)
body: <p>I have a case when there is a number of points on the map and each of them has a "tooltip", that is always shown, which is implemented as a div, that's rendered in (onto?) floatPane, which means, that these divs are rendered above everything. I have a marker, that must not be occluded by these divs, but as of now, it is rendered in overlayImage pane.</p>
  
  <p>What would be th most painless way to make it appear on top of everything? It also has to be able to receive mouse events (click, dragdrop).</p>
