Hi, Aoshi Xu
Thanks for your reply.
Generally, when the Stable version is updated to the same version number as the Canary version, the feature will usually be added (the Stable version typically updates to a major version every two months or so). Meanwhile, please provide feedback to the developers about the need for this feature to ensure it is not removed when it is pushed to the Stable version.
