Merge request assignee is not notified (by email) of pipeline failures if pipelines were authored by someone else. This is a major problem if the person who set the merge request to be merged is out of office and can't respond to pipeline failures. In such cases it's the responsibility of the merge request assignee to merge the merge request and restart or start a new pipeline. To solve this we should always notify merge request assignee(s) of any pipeline failures when merge request has been set to auto merge and has a pipeline merge check.
