Describe the bug

So basically after updating to 0.34.0 from 0.33.0 I get the following error message (redacted):

Error: Failed to load url [REDACTED]/tests/unit/DarkModeSwitch.test.ts (resolved id: [REDACTED]/tests/unit/DarkModeSwitch.test.ts). Does the file exist?

Contrary to what the error message suggests, the file does exist.
I believe this is due to #3491 as it does work when using node instead of jsdom or happy-dom, suggesting the use of the web transform mode instead of ssr is what's causing this.

Note: 0.34.1 doesn't fix the issue.
