Having an empty resource: ```wit interface execution { resource join-set-id { // id: func() -> string; } new-join-set: func() -> join-set-id; } ``` Calling `new-join-set` from a JavaScript guest fails with an error: `ReferenceError: import_execution_1_0_0$JoinSetId is not defined`. This is because the generated `initializer.js`does not contain `class import_execution_1_0_0$JoinSetId {...}`, but tries to use it in the generated `new-join-set` function: `var rsc2 = new.target === import_execution_1_0_0$JoinSetId ? this : Object.create(import_execution_1_0_0$JoinSetId.prototype);` The workaround is to add a function, which triggers the `class` generation. Tested with componentize-js version 0.18.2 .
