does this flip in RTL?

[dpapad, 2016/03/22 20:39:09]

Just tried this. Something weird is happening. The 1st time the menu opens at a
clearly wrong position. Then, closing and re-opening the menu makes it look
correctly. Added a TODO to keep track (BTW search engines similar menu does not
open at all in RTL).

+            opened="{{menuOpened}}">
+          <div class="dropdown-content">
+            <paper-item on-tap="onViewTap_">
+              $i18n{certificateManagerView}
+            </paper-item>
+            <paper-item hidden$="[[!canEdit_(certificateType)]]"
+                on-tap="onEditTap_">
+              $i18n{certificateManagerEdit}
+            </paper-item>
+            <paper-item on-tap="onExportTap_">
+              $i18n{certificateManagerExport}
+            </paper-item>
+            <paper-item hidden$="[[!canImport_(certificateType)]]"
+                on-tap="onImportTap_">
+              $i18n{certificateManagerImport}
+            </paper-item>
+            <paper-item hidden$="[[model.readonly]]"
+                on-tap="onDeleteTap_">
+              $i18n{certificateManagerDelete}
