如何在不删除空白TinyMCE的情况下使用paste_data_images？

Question

I want to use paste_data_images as true and I successfully do that but the issue that when I copy codes it's removed the white spaces.

paste_data_images == true:

paste_data_images == false:

.colorpicker {
    width: 356px;
    height: 176px;
    overflow: hidden;
    position: absolute;
    background: url(http://www.aaronolin.com/codepen/colorpicker/images/colorpicker_background.png);
    font-family: Arial, Helvetica, sans-serif;
    display: none;
    z-index: 999999999;
    top:20px;
}
.colorpicker_color {
    width: 150px;
    height: 150px;
    left: 14px;
    top: 13px;
    position: absolute;
    background: #f00;
    overflow: hidden;
    cursor: crosshair;
}

How can use paste_data_images true without removing the white spaces TinyMCE?
