setContent function alway remove last new line in insert delta

[Kisama]

When I input new line into last of content and add to quill, quill automatically remove last new line

I found setContent function in quill.js alway remove last "\n"

It is add commit id f64a8f2 for fix #1065

I can't understand why quill always last new line?
Is there any one know why quill remove last new line?

when lastOp is newline, setContents remove lastOp.
anyone know why quill remove lastOp? It looks like weird

  setContents(delta, source = Emitter.sources.API) {
    return modify.call(this, () => {
      delta = new Delta(delta);
      let length = this.getLength();
      let deleted = this.editor.deleteText(0, length);
      let applied = this.editor.applyDelta(delta);
      let lastOp = applied.ops[applied.ops.length - 1];
      if (lastOp != null && typeof(lastOp.insert) === 'string' && lastOp.insert[lastOp.insert.length-1] === '\n') {
        this.editor.deleteText(this.getLength() - 1, 1);
        applied.delete(1);
      }
      let ret = deleted.compose(applied);
      return ret;
    }, source);
  }
