Detect line split from gmail in clipboard (angular)

I'm trying to allow users to paste from gmail into a field, and detect line breaks. It does not need to be a text area, I just want to detect the line breaks.

The problem is that when a user pastes something like below...clipboard does not seem to detect the break (even if user had hit enter in gmail)

Item 1 
Item 2 
Item 3

To detect it, the user seems to have to have hit enter twice...like below:

Item 1

Item 2

Item 3

Is there a way to detect line breaks from gmail?

Below seems to work for notepad, inbox and other areas where I copy from.

Stackblitz Demo

Component:

<input type="text" placeholder="paste items here" (paste)="onPaste(i, $event, $event)">

<div *ngIf="itemArray.length > 0">
Item list:
</div>

<div *ngFor="let item of itemArray">
  
</div>

TS:

itemArray = [];

  onPaste(i, event: ClipboardEvent, value) {
    let clipboardData = event.clipboardData;
    let pastedText = clipboardData.getData('text/plain').split("\n");
    pastedText.forEach(item => {
      item = item.toString()
      item = item.replace(/(\r\n|\n|\r|\s\r|\r)/gm, "")
      this.itemArray.push(item) 
    })
  }
