Describe the Bug

I have encountered the same bug that was fixed three years ago: #3787

In an astro component, it is not possible to import an interface or a type from a typescript file.

The behaviour is the same:

• It does not matter if .ts is included or not (import x from "./x.ts" vs import x from "./x");
• It does not matter if the export is default or not;
• It does not work neither with export type nor `export interface;
• Imports and exports of any other JS native items (functions/objects/etc) work perfectly;

The only difference is that the “Weird workaround” (to add any other non-TS export in the file) does not work anymore.

What's the expected result?

Interfaces and types should be able to be imported as it is convenient to use these repeatable items in different components.

TypeScript types don't have runtime values, as such it's normal that they'll always be undefined when trying to console.log them.

In an editor with intellisense, you'll get a warning when trying to do so:

The actual type works fine:
