Why am I able to implement bidirectional 3.3V or 3.0V I/O in Bank 3C in Intel® Stratix® 10 GX 400 density devices?

Description

Due to a problem in the Intel® Quartus® Prime Pro Edition Software version 22.3 and earlier, no error message is given if you implement bidirectional I/O in Bank 3C in Intel® Stratix® 10 GX 400 density devices. 
As per Intel® Stratix® 10 General Purpose I/O User Guide, Bank 3C in Intel Stratix 10 GX 400 density devices only supports unidirectional single-ended I/O with the 3.3 V or 3.0 V I/O standard.
