This works as designed. The intention of Top Level implies, that the Control-node has basically no other Cotrol as parent. The documentation of top_level already states: "The CanvasItem will effectively act as if it was placed as a child of a bare Node." The documentation of MOUSE_FILTER_PASS could be improved by mentioning this behavior of top_level.

@Sauermann, I think documentation for top_level should be adjusted as well. Currently it mostly talks about drawing, so I thought parent example was also just for drawing (like z_index). probably better to add that it also affects inputs events.
