Question: This is a report about a problem which occurred in the comments to [Double Integrals](https://math.stackexchange.com/questions/40520/double-integrals/40524#40524). user6312's comment contained some latex code. I guess he forgot to type a single $ sign with the effect that everything non latex got latexfied and the other way round. (To see the problem in action take a look at the comments following this question)

The end effect (at least in firefox 4) is a comment which does not stay within the allocated column (in fact also the other comments to the questions get screwed up). It is virtually impossible to enlarge the window to such an extend that one gets access to the delete button. 

Is it possible to get the comments formatted in the allocated column (that a single long line does not make all the other lines long)?
An alternative would be to put the signature (and thereby the delete button) on a new line such that it will be always visible.

Answer: 
In most cases, you can just click on the offending line and highlight it towards the right to scroll to the right. I don't think that it would be good to break long formulas arbitrarily.

So taking into account Theo's comment, I fully support the request for the shift of the delete sign to the next line.
The comment display needs to be compact, so adding another line to every single comment to address this rare user input error case -- that applies only to sites with MathJax enabled to boot -- is untenable.

Simple solution: when you see this happen, simply click 'edit' and correct the error, or flag it for moderator attention. While users can only edit comments for 5 minutes after posting, moderators can edit any comments at any time.

edit: perhaps a better solution would be to detect and close any unclosed `$$` pairs in comments?
