Другая тема для списка тем личных сообщений?

Большое спасибо, мне удалось почти всё настроить с помощью компонента темы:

<script type='text/x-handlebars' data-template-name='topic-list-header.raw'>
    <tr class="topic-list-header-row">
      {{~raw-plugin-outlet name="topic-list-header-before"~}}
      {{#if bulkSelectEnabled}}
        <div class="bulk-select">
          {{#if canBulkSelect}}
            {{raw "flat-button" class="bulk-select" icon="list" title="topics.bulk.toggle"}}
          {{/if}}
        </div>
      {{/if}}
      {{raw "topic-list-header-column" order='default' name='topic.title' bulkSelectEnabled=bulkSelectEnabled showBulkToggle=toggleInTitle canBulkSelect=canBulkSelect}}
      {{#if showLikes}}
          {{raw "topic-list-header-column" sortable='true' order='likes' number='true' forceName=(theme-i18n 'likes')}}
      {{/if}}
      {{#if showOpLikes}}
          {{raw "topic-list-header-column" sortable='true' order='op_likes' number='true' forceName=(theme-i18n 'likes')}}
      {{/if}}
      {{#if topic.isPrivateMessage}}
          {{raw "topic-list-header-column" order='posters' forceName='Participants'}}
      {{/if}}
      {{raw "topic-list-header-column" sortable='true' number='true' order='posts' forceName='Replies'}}
      {{raw "topic-list-header-column" sortable='true' order='activity' forceName='Last Post'}}
    </tr>
</script>


<script type='text/x-handlebars' data-template-name='list/topic-list-item.raw'>
    {{#if bulkSelectEnabled}}
      <td class="bulk-select topic-list-data">
        <label for="bulk-select-{{topic.id}}">
          <input type="checkbox" class="bulk-select" id="bulk-select-{{topic.id}}">
        </label>
      </td>
    {{/if}}
    
    <td class='main-link clearfix topic-list-data'>

      {{raw "topic-status" topic=topic}}

      {{~#if showTopicPostBadges}}
        {{~raw "topic-post-badges" unreadPosts=topic.unread_posts unseen=topic.unseen url=topic.lastUnreadUrl newDotText=newDotText}}
      {{~/if}}
      {{discourse-tags topic mode="list" tagsForUser=tagsForUser}}
      {{#if expandPinned}}
        {{raw "list/topic-excerpt" topic=topic}}
      {{/if}}
      <div class='creator'>
        {{#unless hideCategory}}
          {{#unless topic.isPinnedUncategorized}}
            {{category-link topic.category}}
          {{/unless}}
        {{/unless}}
        {{~#if topic.creator ~}}
          <a href="/u/{{topic.creator.username}}" data-auto-route="true" data-user-card="{{topic.creator.username}}">{{topic.creator.username}}</a> <a href={{topic.url}}>{{format-date topic.createdAt format="tiny"}}</a>
        {{~/if ~}}
        {{raw "list/action-list" topic=topic postNumbers=topic.liked_post_numbers className="likes" icon="heart"}}
      </div>
    </td>
    
    {{#if showLikes}}
      <td class="num likes topic-list-data">
        {{#if hasLikes}}
          <a href='{{topic.summaryUrl}}'>
            {{number topic.like_count}} {{d-icon "heart"}}
          </a>
        {{/if}}
      </td>
    {{/if}}
    
    {{#if showOpLikes}}
      <td class="num likes topic-list-data">
        {{#if hasOpLikes}}
          <a href='{{topic.summaryUrl}}'>
            {{number topic.op_like_count}} {{d-icon "heart"}}
          </a>
        {{/if}}
      </td>
    {{/if}}
    
    {{#if topic.isPrivateMessage}}
      {{raw "list/posters-column" posters=topic.featuredUsers}}
    {{/if}}
    
    {{raw "list/posts-count-column" topic=topic}}
    
    <td class="last-post topic-list-data">
      <div class='poster-avatar'>
        <a href="{{topic.lastPostUrl}}" data-user-card="{{topic.last_poster_username}}">{{avatar topic.lastPosterUser imageSize="medium"}}</a>
      </div>
      <div class='poster-info'>
        <a href="{{topic.lastPostUrl}}">
          {{format-date topic.bumpedAt format="tiny"}}
        </a>
        <span class='editor'><a href="/u/{{topic.last_poster_username}}" data-auto-route="true" data-user-card="{{topic.last_poster_username}}">{{topic.last_poster_username}}</a></span>
      </div>
    </td>
</script>

Похоже, что условие #if topic.isPrivateMessage не работает для topic-list-header, поэтому аватары участников личных сообщений отображаются как ожидалось, но в заголовках отсутствует тег <td>, из-за чего всё смещается.
