Position of the selection rectangle when using polyline

Hi everyone,

when selecting an entity with trails as polyline, selection rectangle positioned as below. Is it possible to position the rectangle there, where the head (billboard) is?

**My entity options = **{

    position: position,
    billboard: symbol,
    polyline: trailPolyline


I can imagine having the polyline as a separate entity would solve this, I don’t think there’s an easy way to customize where the selection indicator focuses.

One potential work-around is to create an invisible entity as the billboard, and have it so when you select the visible entity, it detects that and automatically selects the invisible one, so the selection indicator is in the right place.

Can you put together a Sandcastle example of this? You can go to https://cesiumjs.org/Cesium/Apps/Sandcastle/index.html, put together your code example, and click “Share” to paste your link here. Then we can open a GitHub issue with a feature request perhaps.
