自定义复选框 - 在IE11中看不到SVG背景图像

Question

我正在尝试根据Bootstrap 4自定义表单制作纯css自定义复选框。复选框在除Windows11上的IE11之外的所有浏览器上都能正常工作（IE11 + Windows 7正常工作）。奇怪的是：当我使用鼠标光标鼠标选择所有文本或我调整浏览器窗口大小时，它开始工作 - 滴答声神奇地出现。

这就是我设法做的事情：

.custom-checkbox {
  position: relative;
  display: block;
  min-height: 30px;
  padding-left: 40px;
  padding-top: 4px;
}

.custom-checkbox .custom-checkbox-input {
  position: absolute;
  z-index: -1;
  opacity: 0;
  box-sizing: border-box;
  padding: 0;
  margin: 0;

  background-position: center center;
  background-size: 65% 65%;
}

＆＃13;

<div class="custom-checkbox">
  <input type="checkbox" class="custom-checkbox-input" id="customCheck1">
  <label class="custom-checkbox-label" for="customCheck1">
      Check this custom checkbox
    </label>
</div>
