For a project:

foo.ts

export interface Foo {
    abc: number;
}

export function doFoo(callback: (x: Foo) => void) { }

index.ts

import { doFoo } from "./foo";

class Bar {
    bar() {
        doFoo(x => this.baz(x))
    }
}

1. Trigger the declare method quick fix on baz

Expected behavior:
An import for Foo is added to the top of the file:

import { doFoo, Foo } from "./foo";

class Bar {
    bar() {
        doFoo(x => this.baz(x))
    }
    baz(x: Foo): void {
        throw new Error("Method not implemented.");
    }
}

Actual behavior:
An inline import is added:

import { doFoo } from "./foo";

class Bar {
    bar() {
        doFoo(x => this.baz(x))
    }
    baz(x: import("./foo").Foo): void {
        throw new Error("Method not implemented.");
    }
}
