This case is doubly-blocked, first by https://github.com/llvm/llvm-project/blob/f81f47e3ff29598fdf58cde94ccf2c7d4be53df5/llvm/lib/Transforms/InstCombine/InstCombineCasts.cpp#L176-L184 which checks for a comparison with same types and then https://github.com/llvm/llvm-project/blob/f81f47e3ff29598fdf58cde94ccf2c7d4be53df5/llvm/lib/Transforms/InstCombine/InstructionCombining.cpp#L1696-L1709 blocks specifically the min/max pattern.
