Describe the bug

I'm a bit at a loss at what's going on - in a project I have using vite 4.4.0 or 4.4.1 breaks decorators in TypeScript, but going back to 4.3.9 fixes the issue.

All I'm getting on 4.4.0 is SyntaxError: Invalid character: '@' (on some code on our end that uses decorators), while in 4.3.9 everything works.

What is extra weird is that I can't reproduce the issue on StackBlitz even with the same setup / configs in place. I've included my tests so far nonetheless, as I can 100% reproduce the issue locally by switching between vite 4.4.0 and 4.3.9 as dependency.
