Exceptions in batch no longer are shown on the page: Javascript error
Fixed
where we had to use olivero as the test them because the message.js does not work with the stark theme.
This is because core/modules/system/templates/status-messages.html.twig does not print anything under the top level div if there are no messages.
in core/misc/message.js we have
return wrapper.innerHTML === ''
? Drupal.Message.messageInternalWrapper(wrapper)
: wrapper.firstElementChild;
But wrapper.innerHTML !== '' because there is return character. Any other character would also make it break. So in this case wrapper.firstElementChild will be NULL.
We could change the template but any contrib or custom template with this would also break.
Check wrapper.childElementCount === 0 instead of wrapper.innerHTML === ''

No test failure is probably a good sign.
Could steps to reproduce be added please.
Thanks for adding those! Was previously tagged for tests too in #3
