selector 建议将title的赋值，建议使用v-html，与x-input一致

[CodLee]

<label
      :for="`vux-selector-${uuid}`"
      class="weui-label"
      :class="labelClass"
      :style="cleanStyle({
        width: $parent.labelWidth,
        textAlign: $parent.labelAlign,
        marginRight: $parent.labelMarginRight
      })"   >
      <!-- {{ title }} -->
      <span v-html="title"></span>
    </label>
