Demo doesn't work below iOS 16.4

(And neither does my app, which is my real problem - only tried it with the demo because I wanted to see if I could isolate what was going on.)

On building the demo and launching it into the simulator on versions below 16.4 I get the following screen:

and the following log. It works on 16.4+

Nothing in that log says anything relevant to me and I don't see how it's related to the .inspectable change in 16.4.

Xcode Version 15.3 (15E204a)

And the problem is that the demo doesn't include the es-module-shims needed to make it work on older Safari or WebViews.

Neither did my web app, which has been upgraded over several versions of Rails/Turbolink/Turbo.

Thanks for the report! Feel free to open a PR that adds the shims to the demo app.
