[User experience] /** */ completion problem.

## Description

When I disable this extension, I can type `/**` and enter for:

```js
/**
*
*/
```

but when I enable this extension, this feature is break, like the demo below.


I have to type `/**`, then `left key` to close the completion, and then `right key` and enter for what I want.

## Wanted

Don't break the original feature or give the:

```js
/**
*
*/
```

completion highest priority.

Reproduce the completion behavior in VS Code with the extension disabled and enabled, using the /** example and the linked demo as reference. Trace the extension's completion handling to find where it overrides the built-in JSDoc completion; done means enabling the extension still produces the /**, *, and */ block without the extra left/right key workaround.
