Code Insights: have to click multiple times on line charts
Created by: unclejustin
When viewing a line chart, sometimes multiple clicks are needed to actually open the URL.
This is probably related to how we have to re-shuffle the line series SVGs to make the currently hovered series "on top" of the others. This is because SVGs do not recognize z-index. So we have to actually re-order the dom and put the hovered series last for it to render on top.
