(Non-security) Bug fixes and new features go into 2.x - so could someone please check, if the issue still exists in 2.x or has been fixed already?
Also please ensure there are clear steps to reproduce the issue. Perfect would be to have tests showing the issue exists and will be fixed forever then ;) Thank you!
