Debugging Browser Tests doesn't work in project setups #691
Description
Describe the bug
I'm having an issue debugging into a test when run in browser mode and my projects are setup using projects.
The test runs, and reports a success result, but never breaks into the debugger. I eventually after a timeout recieve an error saying Cannot connect to the target at localhost:9229: Could not connect to debug target at http://localhost:9229: Could not find debuggable target from VSCode.
This may be related to #689 as it's workspace/project related, but didn't report anything about debugging.
Reproduction
I've narrowed it down to something to do with the Vitest Project setup.
https://github.com/Alanoll/vitest-vscode-project-repro
The repo currently triggers the bug.
If you modify the vite.config.mts at the root and comment line 40, it will use a non-project configuration and work.
