Answersection requests are all sent at the same time

When a user visits an exam page with many cuts very many requests are being sent at the same time. A decent example for such an exam might be https://exams.vis.ethz.ch/exams/8ha5oyyb.pdf which has 100 cuts which results in 100 HTTP requests being sent at the same time. I would suggest that answersection requests are loaded sequentially or answersections only load their data when they are in the user viewport.
