Dart2JS interop breaks if there are no classes annotated with @JS #37576
Description
Was trying to reproduce a different issue and was unable to use js iterop at all until I had some class annotated with @JS() regardless of wether that class was used.
VM362 main.dart.js:1001 Uncaught TypeError: v.getIsolateTag is not a function
at VM362 main.dart.js:1001
at Object.a.<computed> (VM362 main.dart.js:27)
at Object.bh (VM362 main.dart.js:617)
at Object.bk (VM362 main.dart.js:626)

So, for instance, if I only have top level methods annotated then getIsolateTag function is not written and the interop does not work.
