How do I let vscode show default value in jsdoc

I notice vscode has a closed issue for this "Show default values in jsdoc quick-info."

But I did what that issue said in my jsdoc

* @param {string} [param.method="GET"] - request method

While in the other js file when I hove over to the documented method, I don't see the default value.

So how can I let vscode show default value?

Found another open issue Include Default Parameter Values in Signature Help so I guess I can't right now.
