I added an unused import in app.component.ts and ran the command `ng g @angular/core:cleanup-unused-imports` and the imports array got duplicated.

**Before:**
`
import { Component } from '@angular/core';
import { RouterOutlet } from '@angular/router';
import { UnusedComponent } from './unused.component';

@Component({
    selector: 'app-root',
    imports: [RouterOutlet, UnusedComponent],
    templateUrl: './app.component.html',
    styleUrl: './app.component.css'
})
export class AppComponent {
  title = 'cleanup-unused-imports';
}
`

**After:**
`
import { Component } from '@angular/core';
import { RouterOutlet } from '@angular/router';


@Component({
    selector: 'app-root',
    imports: [RouterOutlet][RouterOutlet],
    templateUrl: './app.component.html',
    styleUrl: './app.component.css'
})
export class AppComponent {
  title = 'cleanup-unused-imports';
}
`

The line with imports contains two arrays of [RouterOutlet] instead of one.
