I've worked on this in SIT project (https://sit.fyi https://sit.fyi). While the core is generalized, the very first module available for it is issue tracking and I've been using it for a few months now. It enabled some scenarios previously difficult/impossible to achieve -- for example, merge requests can contain updates to issues as well, allowing one to make non-trivial updates to issues once their patch is merged in (for example, open a dozen of new issues [todo list for improving the new feature], leave comments, etc.)
