Hi guys, I found another bug.
When writing a comment on a task, and previewing it, if I click the preview button many times (I can be impatient and we have a very slow connection here) it will load the preview that many times afterwards:

I can't see the error in production, are you using your own instance? which browser are you using?
thanks
We are not using our own instance. I'm using Chrome 48.0.2564.116 (64 bit) on Mac OSX 10.11.3.
Here is an ugly gif showing it. I wrote "lalala", then clicked the preview button a bunch of times, three preview boxes appeared. 
thanks @juanstiza
we've found the bugs, it's already fixed in the master branch and it will be in production in the next release
Glad to help!
