Drupal CMS just ran into a nasty bug where submitting a webform dies with a fatal error if XB is installed, because:
Error: Call to undefined method Drupal\experience_builder\EntityHandlers\ContentTemplateAwareViewBuilder::buildElements() in _webform_token_get_submission_values() (line 250 of modules/contrib/webform/webform.tokens.inc).
It turns out that the view builder for webform_submission content entities implements a special interface specific to Webform (\Drupal\webform\WebformSubmissionViewBuilderInterface), which XB doesn't check for (and wouldn't be able to do anything about if it did).
XB should respect a supports_content_templates flag on the entity type definition. It should default to TRUE, but if it's FALSE, XB should not change its view builder, even if the entity type otherwise checks all the boxes that would be needed for it to use content templates. This would give Webform a way to prevent horrible breakages in the short term, while giving it the leeway it needs to properly integrate with content templates (if, indeed, it ever decides to support them for webform submissions).

This sounds very like a subset of 📌 Allow XB to be used on all node types Active .
What are the steps to reproduce? Does this require creating a ContentTemplate for webform_submission content entities? 🤔
