Fusion
I've had a reoccuring issue related to selection filters and copying bodies during an execution preview process. I've isolated the problem to the code below. If you run this code and select a plane, a cylinder will be created on that plane, then it will be copied to a new component. This copy will then cause the selectionCommandInput in the command to select the body, not the original plane. I can't understand why this is being selected but it causes an input change and in a large system causes many bugs. It also changes the body color which is undesirable. Can someone explain how to avoid this or correct the bug in the API?
Here is the sample code, and an image of the problem. Note that the selectionCommand has filters for planes but clearly the body is selected. When I start this command I just select one of the origin planes and watch the preview execute, once the copy is completed the body is "magically" selected.
