Problem/Motivation
When a module has Views plugins, e.g. a display extender, its presence in the system is listed in the views.settings config objects in the "display_extenders" element. When
Steps to reproduce
Install Metatag Views, which is part of Metatag. Alternatively, install the views_test_data test module.
Enable the new display extender.
Export the configuration to an install profile.
Install a new site using the install profile.
What should happen:
The site installs properly and the display extender is enabled as expected.
What actually happens:
An error will be shown and the installation will fail with an error like the following:
Uncaught PHP Exception Drupal\Component\Plugin\Exception\PluginException: "Plugin (metatag_display_extender) instance class "Drupal\metatag_views\Plugin\views\display_extender\MetatagDisplayExtender" does not exist." at core/lib/Drupal/Component/Plugin/Factory/DefaultFactory.php line 97
Proposed resolution
Remove Views' ability to enable or disable display extender plugins, so that they're always available.
