SPI Master fails to read MISO correctly on Mode 3

We might posted that:

under the wrong forum ... I guess this is the better place

The problem is, that ESP32-S3 samples the MISO line in MODE 3 on the falling edge, not on the rising edge as it is defined and documented.

We are right now not sure if this is a bug in the ESP-IDF or in the ESP32-S3 itself.
