Using Jacdac LED blocks in ON START

someone mentioned ( not sure it here or on Github ) that whenever they put any Jacdac LED blocks in ONSTART they led did not light up.

I seem to remember someone else thought it might be due to the Jacdac software not fully starting until after the ONSTART had finished?

I have found that if you put a SET LED BRIGHTNESS block, with a value greater than 0 ,before any LED block in ONSTART, the led will now display

I don’t know if this applies to the previous versions of Jacdac as well but thought it might be useful for someone!
