This will help people understand your PR and can be used as a start for the documentation. Additionally (see https://symfony.com/roadmap): - Bug fixes must be submitted against the lowest maintained branch where they apply (lowest branches are regularly merged to upper ones so they get the fixes too). - Features and deprecations must be submitted against the master branch. --> According to #23210 (comment) we add a new flag in the `Question` class to be able to not trim the answer.
