bug: Generation of src/components.d.ts typing broken in latest build

Prerequisites

• I have read the Contributing Guidelines.
• I agree to follow the Code of Conduct.
• I have searched for existing issues that already report this problem, without success.

Stencil Version

4.19.0

Current Behavior

The generated src/components.d.ts file is corrupt, with missing identifiers in the import and export statements. For example:

import { HTMLStencilElement, JSXBase } from "@stencil/core/internal";
import {  as BBox } from "geojson";
export {  as BBox } from "geojson";
export namespace Components {
    interface AppHome {
    }
    interface AppProfile {
        "bbox": BBox;
    }
    interface AppRoot {
    }
}
...

Expected Behavior

The src/components.d.ts file should be built correctly.

If you switch back to @stencil/core@4.18.0 then the issue is no longer present.
