Describe the bug

When enabling the merge_imports option in SWC's compression transform, imports are being reordered incorrectly and placed after their usage in the code. This breaks the expected execution order and make output not aesthetically pleasing.

Input code

import { v1 } from 'a';
import { v2 } from 'b';
import { v3 } from 'b';
import { v4 } from 'c';

console.log(v1, v2, v3, v4);

Expected behavior

Actual behavior

import { v1 } from 'a';
import { v4 } from 'c';
console.log(v1, v2, v3, v4);
import { v2, v3 } from "b";

Problem Analysis

• Semantic Breaking: The transformation changes the semantics of the program by altering the execution order. The import from module 'b' is placed after imports from 'a' and 'c', which changes the original import order.
• Imports After Usage: The merged import import { v2, v3 } from "b" is placed after the console.log statement where these variables are used. This is not aesthetically pleasing.
