鸿蒙的WebView会遮挡其他控件问题

我的资源配置是这样的。只要webview的高度比scrollview的高度高，则会覆盖下面的button，这是系统bug还是我配置问题？

可以考虑去掉Scrillview看一下

代码如下

<?xml version="1.0" encoding="utf-8"?>
<DirectionalLayout
    xmlns:ohos="http://schemas.huawei.com/res/ohos"
    ohos:height="match_parent"
    ohos:width="match_parent"
    ohos:orientation="vertical">
    <ohos.agp.components.webengine.WebView
        ohos:id="$+id:webview"
        ohos:height="0fp"
        ohos:weight="1"
        ohos:width="match_parent">
    </ohos.agp.components.webengine.WebView>
    <Text
        ohos:height="100fp"
        ohos:width="match_parent"
        ohos:background_element="$color:blue"
        ohos:text="tetxtx"
        ohos:text_size="24vp"
        ohos:text_alignment="center"/>
