I just tested this with Platinum. Regardless of whether or not the original track is collapsed or expanded, the clone is created at the default track height.
Funny, I changed the default track height to test this. The first time is created the clone at the previous default track height. I saved the project and tried again - this time the clone was created at the new default track height.
FWIW, I think I prefer the clone being created at my customized default height to any other option I can think of. Unless alternatives are created in the clone options, but default to the current action.
