Use template in layout layout, but viewtoolbar display exception

#1

I tried using the template in the layout, but the viewtoolbar seems to be missing icons, should I import something else

tags: $:/tags/Layout
title: xxx
name: xxx
description: xxx

\import [[$:/core/ui/PageMacros]] [all[shadows+tiddlers]tag[$:/tags/Macro]!has[draft.of]]

<!-- \import [all[shadows]tag[$:/tags/Image]] -->
<!-- \import [all[shadows]tag[$:/tags/ViewToolbar]] -->

  {{{ [[HelloThere]] ||$:/core/ui/ViewTemplate }}}
