App stops on 'debugger' breakpoint in polyfill.js

[vladimir-kotikov]

When debugging Ionic app in browser (via "Serve" or "Simulate" configuration) app starts and then stops immediately with debugger paused on breakpoint inpolyfill.js

Stack window states that debugger has stopped on 'debugger' statement, however there is no such statement in polyfill.js.

After some investigation this appeared to be a bug in Chrome/Zone.js, tracked here angular/zone.js#446. The good news is that the bug has been already fixed in Zone (angular/zone.js#622) and the fix is available in v0.7.7, so this could be easily mitigated by running npm rm zone.js --save && npm i zone.js --save inside of app folder.

This will be completely resolved once Ionic upgrade their dependencies for default template.

Ok, it appears that aforementioned quick fix won't help because polyfill.js is shipped precompiled with ionic-angular package, a dependency for default template, so to resolve the issue ionic-angular needs to be recompiled with correct zone.js dependency.
