How to handle widget showing E.showMessage with the watchface?

I noticed that it will still redraw them even if a widget shows an E.showMessage above it.

Which widget is this? Widgets really shouldn't do that because it will definitely break things - all the default ones load up a new app to avoid that kind of problem. There's also the notify library that basically does that for you.

But if you added a remove handler to setUI like this: http://www.espruino.com/Bangle.js+Fast+L­oad

Then that would solve the problem, because showMessage would call the remove handler. But then after the message was gone you'd be left with nothing.

... and if the widget was running for pretty much any other app, that would break too - so I wouldn't recommend it
