Atlassian Update – 31-10-2018 Hi everyone, We have recently reviewed this issue and the overall interest in the problem. As the issue hasn't collect votes, watchers, comments, or support cases from many customers during its lifetime, it's very low on our priority list, and will not be fixed in the foreseeable future, i.e. in next 6 months.

The Jira team is focusing on issues that have broad impact and high value, reflected by the number of comments, votes, support cases, and customers interested. Please consult the Atlassian Bugfix Policy for more details. We understand how disappointing this decision may be, but we hope you'll appreciate our transparent approach and communication. Atlassian will keep the issue open and continue to watch this issue for the further updates. Thank you, Ignat Alexeyenko Jira Bugmaster
