bug: `patch` config option doesn't work when `cwd` is on different drive on Windows

Sorry in advance if this is expected behaviour.

E.g. In denoland/fresh#2852, when cwd is D:\a\fresh\fresh\tmp_b61fa28752894c12b453b5f972c17bb2 and patch[0] is file:///D:/a/fresh/fresh/ (same drivers), tests within https://github.com/denoland/fresh/blob/main/init/src/init_test.ts work fine on all platforms. However, when cwd is changed to C:\Users\RUNNER~1\AppData\Local\Temp\8d9bbf697e47eaef (different drives and produced by Deno.makeTempDir()), we get the following error on Windows with the same tests:

error: Relative import path "@std/fmt/colors" not prefixed with / or ./ or ../ and not in import map from "file:///D:/a/fresh/fresh/src/app.ts"
    at file:///D:/a/fresh/fresh/src/app.ts:7:25

While this might not be the only way to solve CI for Fresh, if fixed (and fixable), it'll unblock CI for Fresh.

Can you add a reproduction? It looks like in one case the cwd is within the workspace and for the other it isn't? Maybe the config file isn't being resolved in the second case?
