If you want to be sure that `onRuntimeInitialized` is called you need to
set it on the `Module` object before you import the generated code.
Otherwise the runtime could get initialized before you set
`Module.onRuntimeInitialized`.
In debug builds you should see a warning when these things happen in the
wrong order. See `consumedModuleProp('onRuntimeInitialized');` for how
this is supposed to work.
