transform标签配合keepalive使用时，画面重叠

<div class="content">
                <transition name="fade-transform" mode="out-in">
                    <keep-alive :include="tagsList">
                        <router-view v-if="$route.meta.keepAlive && isRouterAlive"></router-view>
                    </keep-alive>
                </transition>
                <transition name="fade-transform" mode="out-in">
                    <router-view v-if="!$route.meta.keepAlive"></router-view>
                </transition>
                <el-backtop target=".content"></el-backtop>
            </div>
