Code

index.ts:

// upper comment
/*left comment*/ import { foo } from "./foo"; // right comment
// lower comment

foo.ts:

export type foo = "foo":

and enable verbatimModuleSyntax. then run quick fix use 'import type'.

Actual behavior

index.ts:

// upper comment
/*left comment*/ // upper comment
/*left comment*/ import type { foo } from "./foo"; // right comment
 // right comment
// lower comment

upper, left and right comment is duped.

Expected behavior

// upper comment
/*left comment*/ import type { foo } from "./foo"; // right comment
// lower comment
