While they don't just randomly trip, there are issues where they are being used with equipment that has not been evaluated for use with GFCIs. The product standards do not evaluate hard wired equipment for use with GFCIs because the standards assume that the code required EGC will take care of any safety hazard caused by leakage current. It will be a few years before the product standards and the manufactures catch up to the code.
There are even reported issues with the initial use of cord and plug connected stoves and ovens...it seams that the calrod heaters absorb enough moisture on the long ocean trip to the US that when first connected they will trip GFCIs. This is an issue in the 2020 code where the stove receptacle is within 6' of the sink. The problem goes away after the elements have been on for 5 or so minutes, but that will require connection to a circuit that does not have GFCI protection.
