is adding a
theme_escape_and_render() helper function as a BC layer to help theme functions do autoescaping. To avoid coupling the Drupal theme system to Twig, this function is separate from
TwigExtension::escapeFilter(). However, since it performs most of the same functionality, it shares a lot of code.
Refactor the overlapped parts so these two functions can reuse the same code and keep them in sync.
User interface changes
Should be none; internal refactoring with a possible internal-ish API addition.
Data model changes
