Loading GLTF memory could not be freed

I called GC without any effect at all. I took a memory snapshot using the timeline of memory and found that there are many map, bytecodearray and promisereaction objects under the system, and the map has very deep recursion (about more than 100 layers of nodes). According to the memory analysis of the timeline, these memories have not been released. I don’t know what has been done in babylonjs.


I put the snapshot here. Can you help me see what these are? What can I do to free up the occupied memory.
