JSON encoding fails on attr argument in alert modifier

[carson-katri]

When using the alert modifier with an isPresented:

alert(attr("title"), isPresented: attr("presented"), actions: :actions, message: :message)

Compilation fails with the following error:

** (ErlangError) Erlang error: {:unsupported_type, {:isPresented, {:__attr__, [file: "core_components.swiftui.ex", line: 1, module: "", source: "alert(attr(\"title\"), isPresented: attr(\"presented\"), actions: :actions, message: :message)"], "presented"}}}

I don't think stylesheet compilation errors should ever prevent an app from compiling. Instead the styles should be ignored.

Can you pull down main on stylesheet and try again? I am not able to reproduce this locally.

Also, I agree with ignoring errors, however I want to wait until we get closer to 0.4 so that compilation issues are more in our face and we can quickly address them.

@carson-katri can you confirm if this is stil broken?
