DataCloneError when doing a turbo frame navigation

[ibrahima]

This doesn't seem to affect anything as far as I can tell, but I noticed this when investigating #48. In the visitProposedToLocation function, when it's a turbo frame navigation, the options object has objects (request and snapshot) and functions (visitCachedSnapshot) inside of it, which I think can't be cloned, resulting in a DataCloneError being thrown.

hotwire-native-ios/Source/Turbo/WebView/turbo.js

Line 114 in 0bc9f80

this.postMessage("visitProposalRefreshingPage", { location: location.toString(), options: options })

is the line that is affected. I noticed that you can fix it by turning it into a pure JSON object a la https://stackoverflow.com/a/68468806/90551 but I didn't notice any different behavior after doing so. Still, it makes me wonder if something is lost along the way due to this, so I thought I'd report it. I wonder if it makes sense to "clean" objects sent to postMessage somewhere, or if a more pared down options object should be passed in somewhere upstream of this function in this case.

Thanks!

To reproduce:

1. Set up a web app with turbo frame navigation
2. Open the iOS app in simulator
3. Connect to the app via Safari's debugging tools
4. You should see the error in the JS console
