Broken source maps for bundles with packages from node_modules #6526
Description
Describe the bug
I have a workspace with two packages:
pkg-abuild a bundle of its own code and packages from node_modulespkg-bruns test from vitest that import code frompkg-a
The sourcemaps for errors thrown from inside pkg-a report incorrect source locations:
$ pnpm vitest
Error: Test error
❯ Module.foo ../node_modules/.pnpm/base32-decode@1.0.0/node_modules/base32-decode/index.js:5:9
❯ index.test.js:5:3
Running similar code in node JS produces the correct stack trace:
$ node --enable-source-maps script.js
/Users/dmaretskyi/vitest-sourcemap-bug/pkg-a/index.js:5
throw new Error("Test error");
^
Error: Test error
