Question bugs

[RobbinBaauw]

Describe the bug

• After adding a question it is required to refresh the page to add a new question
• Saving a question with multiple correct answers is viewed as single correct answer
• Writing latex in dynamic questions is impossible as it is viewed as a variable
• Hitting save doesn't always remove the question from the to be reviewed questions
• Latex isn't rendered in "edit" menu and in explanation
• Saving questions is sometimes very slow / doesn't work (maybe because of adding extra answers than 2?)
• Images aren't loaded in the preview
• Switching between multiple correct / single correct doesn't work on client
• Questions / answers are not randomized
• Tab on multiple choice doesn't work (to add new answer)

Dynamic questions:

• There's no good support for adding custom functions
• Expression support after $ is non existent
• Upon practicing a dynamic question we get an infinite loop (tab crashes)

It may also be clearer for "Open question - number" that the precision is changed to a delta instead.

Make a result screen for the practice questions. With what you got correct, what you got wrong and an option to retry the questions you got wrong

We're open for merge requests:smile:

But until we find time to overhaul everything, I don't think this issue will be worked on any time soon :(
