Minor I try to edit a cloze question with TeX fragments in it. For example $$ a
over {a+2}$$. Note that all special characters '\,
' are properly escaped. And it also works - I see the preview correctly.
However, when I afterwards try to edit the question once again, all special characters do not contain backslashes in front of them. I see something like: $$ a \over
{a+2}$$. The question is then not displayed correctly.
Thus, in each editing, all backslashes needs be added again.
