Bundler generates incorrect import to current directory

[cornedor]

What version of Bun is running?

1.0.4+745b6b94ee56cad24d475799690cc9a89957d15b

What platform is your computer?

Darwin 23.0.0 arm64 arm

What steps can reproduce the bug?

See this repo: https://github.com/cornedor/bun-incorrect-imports

index.ts will bundle files from two directories using splitting: true. In build/client/Client.js you can see an invalid import.

What is the expected behavior?

Import to a file in the same directory looks like this:

import {
socket
} from "./Socket.js";

What do you see instead?

./ is missing from the import path.

import {
socket
} from "Socket.js";

Additional information

This only happens when that JS file also includes something from another directory.

This might be related to #5344, Socket.js also has a duplicate export.

When I remove the usage of the imported variable from the file, but keep the import, then this is generated:

import"Socket.js";

Note the missing space after import.
