Blank comments (possibly due to long comments) - comments should be limited to 140 chars

Not sure how I reproduced it, possibly comments of certain size

When it's too long, it doesn't even update.

Comments can be limited to 140 chars, and the fieldbox border can become red when it's too long (like orange when it's 120 chars and red (and stops) when it's over the limit)
