Description

Steps to reproduce:

1. Go to edit page: https://wikifunctions.beta.wmflabs.org/wiki/Z11645?action=edit
   • The renderer function fails
   • The failure is shown as an error state of the input field
   • It can be expanded and inspected
   • When collapsed, renderer runs again
     
2. Go to view page: https://wikifunctions.beta.wmflabs.org/view/en/Z11645
   • The renderer function fails
   • The failure is shown below an invisible text
   • When expanded, the error disappears
   • When collapsed, the renderer function doesn't run again, so the state is not visible
     
     

Expected behavior (Acceptance criteria):

• When a renderer error occurs on view, it should be properly communicated
• The error should not disappear
