jquery - 缺少 jQuery-UI 对话框“x”按钮图像（Greasemonkey 4.1beta4 中的用户脚本）

Question

我在 FF57 中使用 Greasemonkey 4.1beta4（最新测试版）。
使用以下脚本^{（供参考，这里是完整的脚本）}
确实创建了对话框，但不幸的是它有一个灰色的空方块，应该是关闭图标：

// ==UserScript==
// @name        jQuery UI dialog
// @include     /^https?:\/\/hg\.mozilla\.org.*pushloghtml.*/
// @require     https://code.jquery.com/jquery-2.1.4.min.js
// @require     https://code.jquery.com/ui/1.12.1/jquery-ui.min.js
// @resource    css http://code.jquery.com/ui/1.12.1/themes/redmond/images/ui-icons_469bdd_256x240.png
// @grant       GM.getResourceUrl
// ==/UserScript==

//  I use an ajax request in the beginning in order to inject the CSS file, otherwise it's blocked by the page's CSP
$.ajax({
    url:'http://code.jquery.com/ui/1.12.1/themes/redmond/jquery-ui.min.css',
    success:function(data){
        $('<style></style>').appendTo('head').html(data);
    }
});

var div = document.createElement('div');
$('div.page_footer').append(div);
div.id = 'dialog';

$('#dialog').dialog({
});

脚本适用的示例页面：
https ://hg.mozilla.org/mozilla-central/pushloghtml?startdate=1+day+ago&enddate=now

我在这个问题中看到问题是我不包括精灵图像（我使用它的主题http://code.jquery.com/ui/1.12.1/themes/redmond/images/ui-icons_469bdd_256x240.png）。

background因此，基于此回复，我一直在尝试将精灵图像（PNG）用作该元素的（CSS）。

以下是我迄今为止的 4 次不成功的尝试（将以下每个部分附加到上面）：

GM.getResourceUrl()（内部async/await，由于 GM 4.x）

（在这种情况下，关闭框只是将颜色变为浅蓝色）

(async function() {
    var stylesheet = `
    <style>
    .ui-dialog-titlebar-close {
      background: url('` + await GM.getResourceUrl("css1") + `') repeat scroll -93px -128px rgba(0, 0, 0, 0) !important;
      border: medium none;
    }
    </style>`;
    $('head').append(stylesheet);
})();

将 PNG 编码为 base64 并尝试附加它：（
在这种情况下，PNG 确实已加载（如 FF'S Inspector 中所示），但关闭框只是将颜色更改为浅蓝色）

var stylesheet = `
<style>
.ui-dialog-titlebar-close {

ajax 请求，并将响应用作 PNG
（关闭框只是将颜色更改为浅蓝色）

$.ajax({

XMLHttpRequest(); （这里是目标 PNG -as blob- 它被页面的 CSP 阻止）

var oReq = new XMLHttpRequest();
