No 24V detection during CAN Bus off state

Configure slave with a cyclic connection.
During cyclic communication short-circuit the data lines. Slave now reports Bus off error TLR_E_DNS_FAL_BUS_OFF_STATE (0xC0620023).

Disconnect 24V bus power. Slave should report 24V error but does not.

Reconnect 24V bus power. Slave should enter cyclic data exchange but stays in Bus off error.

Tested with CIFX 50 and COMX 100.
No such problem in previous versions.
