"Add `extends` constraint" doesn't auto-import dependencies

[DanielRosenwasser]

// @filename: bar.ts
export type MyType = Record<string, string>

export function bar<T extends MyType>(obj: { prop: T }) {}

// @filename: foo.ts
import { bar } from "./bar";

function foo<T>(x: T) {
    bar({ prop: x })
}

Expected

import { bar, MyType } from "./bar";

function foo<T extends MyType>(x: T) {
    bar({ prop: x })
}

Actual

import { bar } from "./bar";

function foo<T extends MyType>(x: T) {
    bar({ prop: x })
}
