Microsoft Support should escalate SharePoint bugs internally, and not ask customers to request bug fixes in UserVoice
Once again Microsoft has reproduced a bug I found in SharePoint, have declared that it's "by design" and asked me to request a fix here in User Voice. There is something very wrong within Microsoft if the Technical support team are unable to escalate issues to the product team. Microsoft need to prioritize fixing the existing core product. Please stop introducing new bugs in new features until the old bugs in the old features are fixed.

I am in this situation currently. I am trying to find a way to talk to the team.
