Generated d.ts file from npm.jsr.io doesn't have Symbol.iterator declaration

[MellKam]

Hi, I recently published a module on JSR: https://jsr.io/@melkam/circular-buffer. I tried using it with other package managers like pnpm and bun. It works fine overall, but I noticed a problem: my CircularBuffer class doesn't include the [Symbol.iterator]() method in its generated .d.ts file, even though it's defined in the source code.

Here’s my source code:

export class CircularBuffer<T> implements Iterable<T, undefined> {
  // ... other class methods
  [Symbol.iterator](): Iterator<T, undefined> {
    return { ... };
  }
}

But the generated .d.ts file looks like this:

export declare class CircularBuffer<T> implements Iterable<T, undefined> {
  // ... other class methods
  // [Symbol.iterator] is missing :(
}

For some reason, [Symbol.iterator] just disappears in the declaration file. To check it out, you can install my package with a package manager other than Deno and inspect /node_modules/@melkam/circular-buffer/_dist/mod.d.ts.

I also tried creating a sandbox example to demo this issue, but it seems JSR modules can’t be installed in StackBlitz right now.
