Title exclusion is overridden if Layout Builder layout has title field

I ran into this problem and was able to solve it by adding the following line of code to the preprocessTitle procedure in /src/Plugin/DsField/Node/ExcludeNodeTitleManager.php

After line 265: $vars['label'][0]['#context']['value'] = '';
Added: $vars['label'][0]['#title']['#context']['value'] = '';

Hope this helps fix the issue

    if ($this->isTitleExcluded($node, $view_mode)) {

      switch ($view_mode) {
        case 'nodeform':
          $node_types = $this->bundleInfo->getBundleInfo('node');

            $vars['head_title']['title'] = new TranslatableMarkup('Edit @nodetype', ['@nodetype' => $node_types[$node_type]['label']]);
