Content entity reference props were introduced behind a hidden dev feature flag in #3591711: a hidden `canvas_dev_er` module exposes `drupalSettings.canvas.devEntityReferenceMode`, and the code editor only shows the "Content entity reference" prop type when that setting is `true` (except for existing components that already use it, so they remain editable). The feature is now ready to be released. This issue tracks removing the feature flag and making content entity reference props public. ### Proposed resolution - Remove the hidden `canvas_dev_er` module and the `drupalSettings.canvas.devEntityReferenceMode` setting. - Always show the "Content entity reference" prop type in the code editor. - Remove the conditional handling that only surfaced the prop type for existing components using it. - Clean up any related tests/fixtures that toggled the flag. ### Related - Introduced in #3591711 > Change record: [#3609370](https://www.drupal.org/node/3609370)
