@Finesse this is approved, but we need to get the snapshots updated first. please run pnpm --filter @rollup/plugin-replace test --u to update the snapshots, and merge the result.

@shellscape The command you provided doesn't work. This command works: pnpm --filter @rollup/plugin-replace test -- -u.

I've run this command and pushed the changes. Sorry for not checking it on my local machine. The misc and sourcemaps snapshots also changed after running the command, but they change the same way when I run the command on master, so I've decided not to push them.
