Searchbar Button with empty text opens debug page

[Moo2Mee]

If I hit the search button without typing anything in the text field, versions 2.7.x open a debug-page:

Symfony \ Component \ HttpKernel \ Exception \ HttpException

PHP 8.4.10
11.45.1
Missing or empty query parameter

[...]
  // Validate the presence and non-emptiness of the query parameter

        if (!$query || trim($query) === '') {

            abort(400, 'Missing or empty query parameter');

        }
[...]

In versions 2.6.x and before an empty Google search would open the Google homepage. This is what I'd prefer.
