[meta] Improve Twig templates

TR → credited rivimey → .

Hi Just added the suggestion in the summary, it sounds good to me.

This is a meta issue. That means patches don't belong here - this issue is just used to track other related issues.

If you want to help out with a specific change, please open a new issue and add it here as a related issue.

As far as your patch, you have two body tags.
Module and key are both required parameters, they will always be set.
Need to keep the attributes.addClass() in there so that people can add custom classes in their preprocess functions.

Again, this is a meta issue, so if you want to help out create that new issue and describe what you want to change and why.

Moved child issues to the current version.
