Vitest borked when inside Deno workspace

Not sure if this is just a misconfiguration or a bug somewhere, so I figure I might as well shoot my shot here.

I installed SvelteKit with Vitest, Playwright and Deno as package manager. I had to change some generated 
npm
 commands to 
deno
, but otherwise this configuration seems to work great.

I then tried to integrate this setup into a Deno workspace, but that didn't work out so great...
deno task -r test:unit gives me this odd error:

The file it's referring to definitely exists and seems to contain the expected content.
It seems to be caused by the @testing-library/svelte/vite import in vite.config.ts, if I comment out that line (and its dependants) things seem to work smoothly again.

Any ideas on how to solve this?
