Svelte 5: $state declared with var in *.svelte.js broken

[Black1358]

Describe the bug

I like to declare states using "var", because they become more noticeable when reading the code. But using this syntax in .svelte.ts files, sometimes the states are "true" when I'm sure they're false. When I output them using console.log, I was very surprised - instead of false, I got the object of the state itself. It definitely wasn't meant to be that way.

Adjacent: #12807. I don't know whether they'd be solved as part of the same work.
