Just curious: what is this fixing (or helping with)?

Aligning the new trashcan so that it is under the other icons above the section.

         -webkit-padding-start: 36px;
         margin-top: 10px;
       }
 
+      .site-header {
+        margin-top: 10px;
+      }
+
       .site {
         margin-top: 3px;
       }
     </style>
-    <div>$i18n{siteSettingsCookieHeader}</div>
+    <div class="layout horizontal">
+      <div class="flex site-header">$i18n{siteSettingsCookieHeader}</div>
+      <div class="secondary-action" hidden$="[[!removeAllIsVisible_(sites)]]">
+        <paper-button on-tap="onDeleteAllSites_" class="secondary-button">
+          $i18n{siteSettingsCookieRemoveAll}
+        </paper-button>
+      </div>
+    </div>
+
     <div class="list-frame vertical-list">
       <template is="dom-repeat" items="[[sites]]">
-        <div class="list-item" on-tap="onSiteTap_" actionable>
+        <div class="list-item">
           <div class="favicon-image" style$="[[computeSiteIcon(item.site)]]"

The whole row area (other than the delete
button at the end) should be clickable to 
do the onSiteTap_. This may need an extra
div wrapping the icon and the item.* text.
That new div would have the on-tap="onSiteTap_"
and the actionable.

Done.

-              on-tap="onOriginTap_"></div>

+          <div class="middle layout horizontal" on-tap="onSiteTap_" actionable>
             <div class="site flex">[[item.site]]</div>
             <div class="secondary">[[item.localData]]</div>
