Highcharts symbol covered by another line
<p>Is there a way to define a symbol that covers another symbol? Or the same with points? I have a symbol that is overdrawn by another symbol, but I want a particular one to appear on top. It appears "last drawn line wins" is the rule, but I may like one line to appear on top at one point, and another at a different time.</p>

<p>In this example fiddle from their page, the idea would be to display the cloud above the sun, z-index wise, without reordering the series data.</p>
