Steps To Reproduce

I am trying to set the textAlign property on a fabric.Text object, but it does not seem to have any effect. Here is my code:
`const canvas = new fabric.Canvas('canvas');

  // 创建文本框
  const text = new fabric.Textbox(
    '这是一段示例文本，用于测试两端对齐，这是一段示例文本，用于测试两端对齐，这是一段示例文本，用于测试两端对齐，这是一段示例文本，用于测试两端对齐，这是一段示例文本，用于测试两端对齐',
    {
      width: 420, // 文本框宽度
      fontSize: 20,
      fontFamily: 'Arial',
      fill: '#333',
      textAlign: 'justify-left', // 最后一行左对齐
      lineHeight: 1.5,
      splitByGrapheme: true,
    }
  );

  // 将文本框添加到画布
  canvas.add(text);`

Expected Behavior

I want like this In photoShop

set left

set justify

Actual Behavior

Without justified alignment for the previous lines

This is the case in the canva.com

Error Message & Stack Trace

  const addTextBox = (option, size = 80) => {
    return new fabric.Textbox(t('addElement.everythingGoesWell'), {
      ...defaultPosition,
      ...option,
      splitByGrapheme: true,
      paintFirst: 'stroke',
      width: 400,
      fontSize: size,
      fill: '#000000FF',
      id: uuid(),
      textAlign: 'justify', // 设置文本两端对齐
    });
  };

我这里也是 textAlign 设置 justify， 明明两端对齐，咋和 “left” 效果一样，

文档上：

this "justify" or "left", set tetAlign, rendering common,
