对齐单选按钮时Flexbox问题

我试图使用包装器上的flex属性对齐单选按钮和它的标签.但是当标签是多行时,它的单选按钮看起来很高.看看屏幕截图.

这是我的html/css

.input-answer-wrapper{}
    .input-answer-wrapper .input-radio-item .radio-label{
        font-size: 12pt;
        color: #36464E;
        display: flex;
    }
    .input-answer-wrapper .input-radio-item .radio-label p{
        display: inline-block;
    }
    .input-answer-wrapper .input-radio-item .radio-label .label-text{
        margin-left: 10px;
    }
    .mg-radio{
      line-height: 16px;
      min-width: 20%;
      padding: 10px 10px 5px 10px;
      cursor: pointer;
    }

    .mg-radio! > input[type=radio] { display: none; }

    .mg-radio input[type="radio"] {
      position: absolute;
      opacity: 0;
    }
    .mg-radio input[type="radio"] + .radio-label:before {
      content: '';
      background: #f4f4f4;
      border-radius: 100%;
      border: 1px solid #b4b4b4;
      display: inline-block;
      width: 1.4em;
      height: 1.4em;
      position: relative;
      top: -0.2em;
      margin-right: 1em;
      vertical-align: middle;
      cursor: pointer;
      text-align: center;
      -webkit-transition: all 250ms ease;
      transition: all 250ms ease;
    }
    .mg-radio input[type="radio"]:checked + .radio-label:before {
      background-color: #64B3F5;
      box-shadow: inset 0 0 0 4px #f4f4f4;
    }
    .mg-radio input[type="radio"]:focus + .radio-label:before {
      outline: none;
      border-color: #3197EE;
    }
    .mg-radio input[type="radio"]:disabled + .radio-label:before {
      box-shadow: inset 0 0 0 4px #f4f4f4;

    }
    .mg-radio input[type="radio"] + .radio-label:empty:before {
      margin-right: 0;
    }

    

        

            
                
                Lorem ipsum..Lorem ipsum..Lorem ipsum..Lorem ipsum..Lorem ipsum..Lorem ipsum..Lorem ipsum..Lorem ipsum..
