* |
* 0 -<----------+ Selection and bookmarks saved.
* |
* |
* 25 -<---+ Exec 1st job of plugin#1 (return false, continuing...).
* |
* |
* 50 -<---+ Exec 1st job of plugin#2 (return false, continuing...).
* |
* |
* 75 -<---+ Exec 2nd job of plugin#1 (only if plugin#2 failed).
* |
* |
* 100 -<-----------+ Re-select bookmarks, clean-up.
* |
* +-------- v ----------+
* | Exec event finished |
* +---------------------+
*
* For the `refresh` event:
*
* * <100: Content-specific commands refresh their job states according
* to the given path. Jobs save their states in the `evt.data.states` object
* passed along with the event. This can be either {@link CKEDITOR#TRISTATE_DISABLED}
* or {@link CKEDITOR#TRISTATE_OFF}.
* * 100: Command state is determined according to what states
* have been returned by content-specific jobs (`evt.data.states`).
* UI elements are updated at this stage.
*
* **Note**: If there is at least one job with the {@link CKEDITOR#TRISTATE_OFF} state,
