As the note says (“The feature will be reconsidered in future versions.”), we will try to bring it back eventually, once we get it in a good shape. Unfortunately right now we have a tremendous amount of confirmed unique regressions coming from this feature (not only in context menus, but also in seemingly unrelated parts of the editor UI) with more getting discovered faster than we can fix them. So we erred on the side of caution and stability.
And you’re right, its shape is much better on Windows than on Mac or Linux.
