For some reason, the above configuration on the Daisy Field results in unreliable behavior from the LED. From my testing, the button bang itself is actually perfectly reliable, but somewhere in the chain an error causes the LED to only turn off sometimes. The error isn't entirely random, since at the very least it's always on when it should be.
The cause of this bug isn't obvious to me at the moment, and it seems to be pretty subtle.
