开发者工具中background-image重复显示问题

问题模块 框架类型 问题类型 操作系统 工具版本
开发者工具 小程序 Bug Windows Stable v1.02.1904090

Bug情况:

当在wxss中为<input>定义了background-image并使用url(data:image/png;base64,........)时,图片可以正确显示,但会重复两次。这个问题只在input标签中测试过,别的情况不知道是不是也这样,且只在开发者工具中出现,真机测试时没有问题。具体情况见代码和截图:


wxml:

<input type="text" name="keywords" maxlength="50" placeholder-class="placeholder" placeholder="快速搜索动作..." bindinput="searchExerciseByKeywords" />


wxss:

.searcharea input {
  width: 100%;
  box-sizing: border-box;
  font-size: 14px;
  line-height: 14px;
  background-color: white;
  border: 1px solid #cccccc;
  border-radius: 5px;
  overflow: hidden;
  height: 36px;
  vertical-align: middle;

      奇怪了,这个bug在代码片段里居然不能重现,我也找不出什么规律。但是在我自己的项目立确实是有问题的。
