💻 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

Additional information about the issue

ts1484 error: 'foo' is a type and must be imported using a type-only import when 'verbatimModuleSyntax' is enabled.

使用 index.ts 和 foo.ts 代码片段重现该问题，启用 verbatimModuleSyntax，并调用 ts1484 快速修复以使用 import type。首先跟踪该诊断的快速修复行为；完成的标准是 import 发生更改，同时不重复上方、左侧或右侧的注释。
