Problem/Motivation
When going to configure the form display of taxonomies with the field_group module enabled on Drupal 10.3.5, we get the exception with the stack trace:
Symfony\Component\Routing\Exception\MissingMandatoryParametersException: Some mandatory parameters are missing ("arg_1") to generate a URL for route "field_ui.field_group_add_taxonomy_term.form_display". in Drupal\Core\Routing\UrlGenerator->doGenerate() (line 190 of core/lib/Drupal/Core/Routing/UrlGenerator.php).

In \Drupal\Core\Routing\UrlGenerator::doGenerate it does this:
$variables = array_flip($variables);
$mergedParams = array_replace($defaults, $this->context->getParameters(), $parameters);
// All params must be given
if ($diff = array_diff_key($variables, $mergedParams)) {
throw new MissingMandatoryParametersException($name, array_keys($diff));
}
The missing parameter is arg_1. When I add $mergedParams['arg_1'] = 'xyz'; instead of the exception there, it creates a URL like /admin/structure/taxonomy/manage/tags/overview/xyz/form-display/add-group for the button to add a new field group.
So, some argument is missing between overview and form_display, but I'm not sure what that should be.
For nodes, the link is e.g. /admin/structure/types/manage/page/form-display/add-group and that doesn't cause any issue. The route for taxonomy terms has the extra /overview/{arg_1} piece in it, but I don't know where this is coming from.
