Annotations/Skeletons do not respect layer order while rendering

In the example below you will probably/might see some point annotations appear and then disappear once the skeleton loads (the red color) even though skeletons are layer 1 and annotations are layer 2. If you toggle visibility on a layer, it will render itself on top of the other layer.

I would expect the layers to always be rendering in layer order with higher layer numbers being rendered on top of lower ones as is the case with image/segmentation layers.
