Reference to undefined variable "Host" in "examples/piu/sound"

[stc1988]

Build environment: Windows
Target device: M5stack,Desktop simulator

Description
I got a reference error when "examples/piu/sound" application launch.

Steps to Reproduce

1. Launch "examples/piu/sound" application.
2. See error.
   examples\piu\sound\main.js (79) # Break: SoundAppBehavior.prototype.onDisplaying: get Host: undefined variable!

moddable/examples/piu/sound/main.js

Line 79 in 157795c

if (undefined !== Host?.Button?.C && undefined !== Host?.Button?.E && undefined !== Host?.Button?.F) { // Kaluga buttons

moddable/examples/piu/sound/main.js

Line 96 in 157795c

if (undefined !== Host?.Touchpad?.B && undefined !== Host?.Touchpad?.E && undefined !== Host?.Touchpad?.F ) { // Kaluga touchpad

You should check if the variable "Host" is defined.

Thank you for the report! I'll get a fix for that into our next push.

I've committed fixes for this one and something similar in examples\drivers\neopixel\main.js. Those fixes will be available in our next open source push.

Thank you again for the report.
