【报Bug】HbuilderX3.7.7中对css语法中对flex布局显示错误的问题

示例代码：

<scroll-view class="more_srocll" :scroll-top="scrollTop"  scroll-y="true" show-scrollbar="false"  
                 :style="{height:idHeight+'rpx'}">

                    </view>  

                    <view class="m_st_c_right">  
                        <view class="m_st_c_tip_view" v-if="item.param[0].name == '上管温度'">

                            <text class="m_st_c_tip" v-if="item.param[1].name != '下管温度'">{{item.param[0].value}}°C</text>

操作步骤：

CSS语法中的bug。怀疑是flex布局的问题

.m_st_c_right{  
            width: 350rpx;  
            flex-direction: row;  
            justify-content: space-between;  
            align-items: center;  
            .m_st_c_tip_view{  
                width: 180rpx;  
                flex-direction: row;  
                justify-content: space-between;  
                align-items: center;  
            }  
            .m_st_c_tip{  
                width: 180rpx;  
                /*background: rgba(0,0,0,0.1);*/  
                color: #343434;  
                font-size: 28rpx;  
                font-weight: 400;  
                text-align: center;  
            }  
            .m_st_c_time{  
                width: 150rpx;  
                /*background: rgba(0,0,0,0.1);*/  
                color: #343434;  
                font-size: 28rpx;  
                font-weight: 400;  
                text-align: center;  
            }  
        }
