Pass state problem in Svelte 5

[Enes5519]

Describe the bug

I have doubts about whether the states are transferred correctly when using a library that I have in Svelte 4 in Svelte 5. While it works without any problems in Svelte 4, it does not work the same way in Svelte 5.

I prepared an app that changes the radio value every second. If you look at the links in reproduction, you can understand the problem exactly.
