Description
Hello,
When mapbox-gl-draw source is getting big, user can observe flickering of drawn features on selection change:
It seems like plugin moves features from one source to another and when there's many features on the map this operation takes time. Maybe for a moment features affected by selection change are not part of any source.
Do you think it is possible to somehow fix this?
**Demo:** https://jsfiddle.net/tpe907dc/
