Hello,
We are having a strange issue with our Jira environment. Our comment replies seem to bug out making it look like they don't submit because they don't reload the page.
For example if we try to reply to a comment on an issue and submit it, the page will scroll up without reloading, with the reply window still open - making it seem as if the reply didn't go through. However, if we manually reload the page afterwards, the response is submitted. Problem is most of the users think the reply didn't go through, so they keep hitting the "Add" button and end up posting the same response multiple times.
I've attached an image of posting a test response to one of the comments. If we type a response, and press "add" button it stays on this same page with this window open.

We are on Jira 6.3.15 running on Centos 7
Thanks.
