Origin: This is a wish from the German Community Wishlist Survey 2017. It did not get voted as a top wish, but because the individual issues it contains are rather small, independent projects, they are recommended for volunteer developers, e.g. to be tackled during the Wikimania Hackathon 2017.
Problem: There are some formatting issues when using the <math> markup. The wish mentioned above lists some issues that are occurring throughout different browsers. These individual issues are subtasks of this task. They can be tackled separately or together.
