Unable to load default and exported from vue templates

Expected Behaviour

I expect to import default and exported interfaces from ts file/portion. It was working on ts-loader 8.x with webpack 4.x and it's failing on ts-loader 9.x with webpack 5.x.

It even works on ts-loader 8.x using webpack 5.x (not recommended since I believe it's not designed for).

Actual Behaviour

Typescript return the error TS2614 when trying to do an import like import HelloWorld, { HelloProp } from './components/HelloWorld.vue';

See the full output:

Steps to Reproduce the Problem

I created a sample to reproduce the working and not working versions:

• ✅ ts-loader 8.x with webpack 4.x: https://github.com/jrbasso/ts-loader-import-bug/tree/ts-loader-8
• ✅ ts-loader 8.x with webpack 5.x: https://github.com/jrbasso/ts-loader-import-bug/tree/ts-loader-8-webpack5
• ✖️ ts-loader 9.x with webpack 5.x: https://github.com/jrbasso/ts-loader-import-bug/tree/ts-loader-9

To reproduce, simply checkout the branch and run npm ci && ./node_modules/.bin/webpack

Location of a Minimal Repository that Demonstrates the Issue.

See steps to reproduce.

Start with the linked minimal repository branches and run npm ci && ./node_modules/.bin/webpack for the ts-loader 8.x and 9.x cases. Compare how src/App.vue.ts imports the default and named HelloProp exports from ./components/HelloWorld.vue; done means the ts-loader 9.x and webpack 5.x case compiles without TS2614.
