Describe the bug

For example:
import { Pose } from "@mediapipe/pose"
const p = new Pose();

Will build to:
const p = new Gu.Pose();

It seems any package name containing a "/" will cause the building process to prepend a name to the new class constructor.

And it will cause TypeError: Gu.Pose is not a constructor.

My current workaround is to remove the name appending after the project is built.

"vite": "^2.9.2"
"vue": "^3.2.25"
