Description

When trying to register an asset bundle extending craft\ckeditor\web\assets\BaseCkeditorPackageAsset, sometimes the bundle isn't properly loaded within craft\ckeditor\web\assets\BaseCkeditorPackageAsset::$ckeditorPackages. When trying to register an identical asset bundle where the only change is the namespace, the package is registered properly. The package is also successfully registered if the body of the craft\ckeditor\Plugin::init() method is placed within the Craft::$app->onInit() callback.

Steps to reproduce

  1. Generate a Craft plugin
  2. Register a BaseCkeditorPackageAsset asset bundle with Ckeditor with varying root namespace.

Additional info

The packages should end up being registered depending on the namespace of the PHP package. While debugging, the plugins with namespace beginning in A/B/C would work, while the Plugins with namespaces beginning in D/E/F/... wouldn't work.

Local modules would always work.
Yii2 Extensions (modules) would always work.

                      The packages should end up being registered depending on the namespace of the PHP package. While debugging, the plugins with namespace beginning in A/B/C would work, while the Plugins with namespaces beginning in D/E/F/... wouldn't work.

                          Description
                          When trying to register an asset bundle extending craft\ckeditor\web\assets\BaseCkeditorPackageAsset, sometimes the bundle isn't properly loaded within craft\ckeditor\web\assets\BaseCkeditorPackageAsset::$ckeditorPackages. When trying to register an identical asset bundle where the only change is the namespace, the package is registered properly. The package is also successfully registered if the body of the craft\ckeditor\Plugin::init() method is placed within the Craft::$app->onInit() callback.
