Devcards not reloading when using code splitting

Dear all,

I have problem when using code splitting and reach Suspense to lazy loading. I created demo project
https://github.com/rpofuk/sample-split-demo.

When I start in parallel:
```shadow-cljs watch app```
```shadow-cljs watch devcards```

And open in browser both:
http://127.0.0.1:8000/#
http://127.0.0.1:3001/#!/demo.sample

Then I make change in demo.components.product-listing

Change on :app is reloaded but in :devcards it is not.

Additionally, if I change part of code that is not lazily loaded then it refreshes. It is only about code that is inside Suspense that is not reloaded.
