This code is loading on mobile and throwing JavaScript errors
On mobile breadcrumbEl doesn't exist, so the reference to breadcrumbEl.children throws an error. Please add a return statement where breadcrumbEl doesn't match anything. Thanks in advance! I can replicate this error on this page when loaded in mobile Jdlrobson (talk) 16:25, 15 February 2019 (UTC)
