0.29.2 "No test suite found in file" thrown in setup files when using experimentalOptimizer: true

[EvHaus]

Describe the bug

I noticed that with experimentalOptimizer: true my setup file is throwing:

 FAIL  setupFile.ts [ setupFile.ts ]
Error: No test suite found in file /home/myproject/setupFile.ts

This is unexpected because the setup file doens't have any test suites.

Reproduction

https://stackblitz.com/edit/vitest-dev-vitest-7pfeua?file=setupFile.ts

To reproduce you'll need vitest configuration to have:

test: {
	deps: {
		experimentalOptimizer: {
			enabled: true,
		},
	},
	setupFiles: ['setupFile.ts'],
}
