💻 Code

/** doc */
function func() {} // or `const func = () => {};`

const obj = { func };

obj.func;
obj.func();

🙁 Actual behavior

With TypeScript 7, hovering over func in obj.func() displays only:

(property) func: () => void

The JSDoc text doc is missing. Signature help inside the same call still shows doc, and hovering over the original function declaration also shows it.

🙂 Expected behavior

Hovering over func in obj.func() should include the JSDoc of the resolved function signature, matching TypeScript 6.0.3 and the native server's own signature help.
