I've got an annoying bug with the RPi4 where when turning my TV to standby it powers off then a few seconds later it powers back on again. It's basically saying you can't leave me 
I've got a debug log with verbose CEC logging on a fresh install. Dmesg here. I've also tried with the firmware mentioned here. I've tried disabling all power options in the CEC options in peripherals.
This only seems to happen when connected to my Onkyo AV amp, if I connect directly to my TV this behaviour doesn't occur. RPi3 behaves as expected.
Obviously early days in RPi4 development but thought I'd put the bug out there. Is there anywhere else I can post this, maybe RPi forum? Github?
