load() not called on reboot?

Been trying to debug this for awhile, with this code:

function onInit(){
    setInterval(function(){
        console.log("X");
    },1000)
}

upload to board, then

save()

disconnect usb and then reconnect, connect to terminal, nothing outputted. If I type

load()

then it the interval prints:

>load()
=undefined
WARNING: --- gap_setScan 0

WARNING: Scan stop failed
WARNING: set rssi scan not implemeted yet

WARNING: has central connection not implemented yet

Pico immediately prints after reconnect without needing to manually kicking it. Im on v1.99. I'll try downgrade the firmware to see if it's a regression.
