path.format({base: ''}) inconsistency with Node

[vjpr]

What version of Bun is running?

0.7.3

What platform is your computer?

No response

What steps can reproduce the bug?

import path from 'path'

const test = 'foo.ts'

const out = changeExtension(test, '.rs')

console.log(out)

function changeExtension(p, ext) {
  const parsedPath = path.parse(p)
  const out = path.format({...parsedPath, base: '', ext})
  return out
}

What is the expected behavior?

$ node .
foo.rs

What do you see instead?

$ bun .

Additional information

base: null works however.
