Bun env-expand doesn't work between env files

[hmidmrii]

What version of Bun is running?

1.1.33+247456b67

What platform is your computer?

Microsoft Windows NT 10.0.22631.0 x64

What steps can reproduce the bug?

my .env is:

A=A
B=B$A

and my .env.local is:

C=C$A

my index.ts file:

console.log(JSON.stringify({
    a: import.meta.env.A,
    b: import.meta.env.B,
    c: import.meta.env.C,
}, null, 2));

Bun does expand the correct variables in .env but doesn't in .env.local

What is the expected behavior?

Bun should expand the variables in .env.local

{
  "a": "A",
  "b": "BA",
  "c": "CA",
}

What do you see instead?

Bun doesn't expand the variables in .env.local

{
  "a": "A",
  "b": "BA",
  "c": "C",
}

Additional information

Bun is expanding each env file separately instead of merging the env files (like env-flow) and then expanding them.
