[Launchpad] Unhandled promise rejection stops pages from rendering

STR:

• open debugger
• in the tab being debugged go to http://todomvc.com/

ER: see the source
AR: editor is blank

When there is a rejection of the onConnect call in launchpad/src/main.js the whole app stops loading. Adding a catch condition should enable proper error reporting and functioning of the loaded app at the same time.
