Version Information
Raised for self-hosted

I have tested the proposed fix on a self hosted Jira and can confirm that it is now working for me, I was able to replicated the issue from master but when using the created branch im the linked pull request the functionality now works

PRJ was me testing as I was taking a quick look into it myself, PRK was using the branch code unmodified.
