When you click on the “Clear cache” link in the K5 panel sidebar, the “Clear cache” page does not maintain the sidebar or the breadcrumb link in <div class="k-topbar">…</div> at the top of the page.
This behaviour does not occur when clicking the default Kirby sidebar links such as “Site”, “Users”, or “System”.
