We expect a fix for this issue to be released in early January for both JIRA Cloud and JIRA Server.
We will update the current behavior to remove the association between Issue Worklogs and the Issue Updated event. This should resolve the problem originally described in this issue.
As I mentioned in my previous update, improving events and email notifications is part of the current JIRA roadmap. A number of you have indicated that there are existing challenges you face with JIRA email notifications beyond this issue. We would love to hear your feedback and suggestions – feel free to contact me directly.
