SymbolActivity icons rendering artifacts


Not only the icons change to black when they are on the same tile as the airplane bitmap, there are also lagging when rendering.

Disabling the sdf param for the airplane icon seems to resolve the issue.
Refs https://github.com/mapbox/mapbox-gl-native/issues/14809. I pulled in changes from https://github.com/mapbox/mapbox-gl-native/pull/15456 and while the icons are not treated as SDFs visually anymore, the rendering performance is still impacted like in the OP:

Is this still relevant? If so, what is blocking it? Is there anything you can do to help move it forward?
