Rotator controller doesn't respect limits

I have implemented a hamlib back end for iOptron alt-az mounts. In testing with Gpredict it appears to work well with my iEQ45 Pro. The only small issue is that if I set minimum elevation to 5 degrees in the Gpredict rotor interface, the program still drives the mount down to zero. Is there a Gpredict issue with minimum elevation? I didn’t see a hamlib method for setting the mount minimum elevation in the mount. Did I miss something?
