Jira roadmap behavior has changed

In previous versions of JIRA (prior to 6.2) you could see a list of issues for each version on the roadmap as described in the documentation:

https://confluence.atlassian.com/display/JIRA062/Browsing+a+Project%27s+Road+Map

It seems this behavior changed in 6.2 (can see the new behavior here https://jira.atlassian.com/browse/JRA?selectedTab=com.atlassian.jira.jira-projects-plugin:roadmap-panel&allVersions=true). In the page source code I can still see the code to allow it to expand which has a link to expand per version but it is hidden.

I also don't see any mention of the change in the release notes:

https://confluence.atlassian.com/display/JIRA/JIRA+6.2+Release+Notes

Could we confirm this was intended behavior get the docs updated and/or provide a fix. We have an issue raised in support and also several users have commented on the docs here:
