[bug] generates a dts error when typeof this is encountered

my code
```ts
export default class {
name: 'foo' | 'bar'

logName(name:typeof this.name) {
console.log(name)
}
}
```

generate dts
```d.ts
declare class export_default{
name: 'foo' | 'bar';
logName(name: typeof this$1.name): void;
}

export { export_default as default };
```

my versions
```json
"devDependencies": {
"tsup": "^7.2.0"
},
"dependencies": {
"typescript": "^5.2.2"
}
```

Reproduce the report with the provided TypeScript class and the listed tsup 7.2.0 and TypeScript 5.2.2 versions, then trace the declaration-generation entry point that produces the shown output. Done means the generated declaration no longer contains an invalid typeof this$1.name reference; no source file or test is named in the report.
