The UI Patterns module adds a #context object to the template variables. But this can cause issue in the future, as it is possible that Drupal Core defines itself a #context array.
@see https://www.drupal.org/project/drupal/issues/2511548#comment-15457093 ✨ Add a "context" array variable to all theme hooks and "#context" array property to all elements to provide optional contextual data Needs work
We get a PHP Fatal error.
Maybe create the context object inside the "ui_patterns_theme_suggestions_alter()" function, but not before?

For information, #context property will not be kept in UI Patterns 2.x because it is used mainly for preprocesses hooks which are forbidden by SDC.
