FDCAN: fdcan_tq_ck < fdcan_pclk requirement

We are using custom board with STM32H735. We were debugging the same issue as this one. In the reference manual RM0468, we discovered this note:

I think this means that even when not using calibration unit, FDCAN kernel clock must be <= than APB1 peripheral clock. My question is why does CubeMX Clock Configuration not check this requirement? Would you consider adding this check?
