参考：VUE3.0之v-for 中的 Ref 数组

<router-link
        v-for="tag in visitedViews"
        ref="tag"
        :key="tag.path"
        :class="isActive(tag) ? 'active' : ''"
        :to="{ path: tag.path, query: tag.query, fullPath: tag.fullPath }"
        tag="span"
        class="tags-view-item"
        @click.middle="!isAffix(tag) ? closeSelectedTag(tag) : ''"
        @contextmenu.prevent="openMenu(tag, $event)"
      >
        {{ tag.title }}
        <span
          v-if="!isAffix(tag)"
          class="el-icon-close"
          @click.prevent.stop="closeSelectedTag(tag)"
        />
      </router-link>

    moveToCurrentTag() {
      const tags = this.$refs.tag;
      this.$nextTick(() => {
        for (const tag of tags) {
          if (tag.to.path === this.$route.path) {
            this.$refs.scrollPane.moveToTarget(tag);
            // when query is different then update
            if (tag.to.fullPath !== this.$route.fullPath) {
              this.$store.dispatch("tagsView/updateVisitedView", this.$route);
            }
            break;
          }
        }
      });
    },
