# mathjax doesn't render in the review section [duplicate]

I recently went to see what is in the queue of the "Suggested Edits" and I saw this:

first I thought that it was just '$' placed wrongly, so I went to edit this myself and saw the following: this part is clearly correct, so it completely ignored the '$\$' that were placed after the ';'.

why does it happens?

• I think it is a bug after all. Same happened with me some days ago, someone edited one of my questions and it looked pretty much like what you saw. – Mohammad Zuhair Khan Jan 6 '18 at 8:37
• If it is considered a bug, it is a longstanding one. One way to mitigate this is, as you articulate, to use the Improve Edit function and preview the proposed changes in that way. Unfortunately this approach is affected by another bug which makes MathJax rendering balky and sometimes fails. – hardmath Jan 6 '18 at 14:30
