Image missing callback impacts rendering of other layers

[LukasPaczos]

In the example above there are 3 layers that rely on one geojson source - circle layer and 2 symbol layers. After clicking the button, one of the images that the top layer uses (garbage bin) is removed from the map and starts to trigger the image missing callback which dramatically impacts the rendering of all layers that are based on this source. Other layers and the render thread itself seem to not be impacted as panning and zooming are smooth.

Bisection points to #14320 as well.

This can be reproduced on lp-image-missing-impacts-other-layers by running the Simple Map example.

Yeah... hmm. The callback gets fired every time a missing icon is needed. So generally this would happen once per tile load but for examples like this where the location is updated every frame I guess it would call every frame. And calling into the main thread is probably what adds this delay.

The render thread could keep track of which images it's already fired the callback for and skip them I think!

The fix got reverted at #15852
