💻 Code

interface A {
    foo: import("./doesntexist.js").Foo;
    get bar(): import("./doesntexist.js").Foo;
}


class B implements A {
// Trigger completion: "implement interface A" display this completion:
// Actual:
// foo: any;
// get bar(): any {
//     throw new Error("Method not implemented.");
// } 

// Expected:
// foo: import("./doesntexist.js").Foo;
// get bar(): import("./doesntexist.js").Foo {
//     throw new Error("Method not implemented.");
// } 
}

🙁 Actual behavior

Triggering completion uses any instead of the unresolved type.

🙂 Expected behavior

Completion should be the unresolved type instead of any

Additional information about the issue

Found in PR https://github.com/microsoft/TypeScript/pull/59440

Start with the completion behavior reproduced in the linked Playground when implementing interface A, focusing on completion getters/setters and property declarations. Compare the actual any output with the expected unresolved import type; done means all shown completions preserve import("./doesntexist.js").Foo instead of using any.
