Build environment: macOS
Moddable SDK version: >= v7
Target device: desktop simulator
Description
Attempting to run any program using Poco ("commodetto/Poco" module) in the simulator results in an error:
Break: SyntaxError: C: xsArg(1): invalid index (in @screen_begin)!
It will run fine on a device, i.e. Moddable Six, but not the simulator version.
Steps to Reproduce
cd $MODDABLE/example/commodetto/textmcconfig -d -m -p sim/moddable_six
Expected behavior
Simulator starts with the demo text appearing on the screen

Other information
I've debugged this down to the ECMA-419 display support being added in v7 of the SDK. The manifest_commodetto.json defaults to defining ECMA419.display: 1 which should use that branch of logic when rendering graphics with Poco. When I set that flag to 0, then the example runs successfully. This leads me to believe the screen module for the simulators wasn't updated to match the expected logic for the ECMA-419 Display implementation, starting with somewhere in the screen_begin method: https://github.com/Moddable-OpenSource/moddable/blob/public/build/simulators/modules/screen.c#L625
