webkit-overflow-scrolling隐藏了绝对定位的div

Question

我将首先给出示例以及屏幕截图:

HTML:

<div class="add-link-box">
<div class="add-link-box-close-button" id="add-link-box-close-button">X</div>
<form name="add-link" id="add-link-form" method="post" action="" enctype="multipart/form-data">
<div style="width: 90%;" class="alink-field">Add A Link</div>
<div class="mobile-form-frame" id="mobile-form-frame">
<div class="alink-field mobile-alink"><label for="link-url">Link Address:</label></div>
<div class="alink-field"><input type="text" name="linkurl" id="link-url" class="add-link-form" 
placeholder="www.awebsite.com"></div>
<div class="alink-field mobile-alink"><label for="link-description">Link Description:</label></div>
<div class="alink-field"><input type="text" name="linkdescription" id="link-description" class="add-link-form" placeholder="my
website"></div>
<div class="alink-field mobile-alink"><label for="link-image">Link Image:</label></div>
<div class="alink-field"><input type="file" name="linkimage" id="link-image" class="add-link-form"></div>
<div class="alink-field"><input type="button" name="submit" value="Submit Link" class="add-link-form" id="add-link-submit"></div>
<div class="alink-field"><input type="reset" name="reset" value="Clear" class="add-link-form" id="reset"></div>
</div>
</form>
</div>

CSS:

.add-link-box{border: 2px #006BB5 solid; color: #006BB5; font-family: bonvenocf; text-align: center; font-size: 16pt; margin: 10px; height: 90%; margin-top: 30px; overflow: auto; -webkit-overflow-scrolling: touch;}

.mobile-form-frame{overflow: auto; height: 90%;}

.add-link-box-close-button{position: absolute; display: block; right: 5px; top: 5px; width: 20px; height: 20px; padding: 2px; line-height: 18px; font-size: 18pt; text-align: center; cursor: pointer; font-weight: bold; color: #FF0000;}

.add-link-box-close-button:hover{color: #FF0000;}

.alink-field{width: 90%; margin: 0px; display: block; padding: 10px; margin-left: auto; margin-right: auto; text-align: center;}

.mobile-alink{text-align: left;}

这是问题所在:

添加-webkit-overflow-scrolling: touch;到mobile-form-frame类时(为了在iOS设备上实现原生滚动),隐藏关闭此div的"X".如果我们删除它-webkit-overflow-scrolling: touch;,它不会.我做了一些搜索,并没有真正找到其他人看到过同样的问题.我不明白为什么这会导致绝对定位的div add-link-box-close-button被遮挡.有谁能帮我解决这个问题？它实际上是iOS上Safari的一个错误吗？

我已经包含了截图来演示我遇到的结果.

编辑:上面的html包含在容器div中 position: fixed;

不是专家，只是一个想法，如果移动“X”z-index 会怎样？你尝试过吗？

也许 X 已显示但不在前台。只是一个想法
