eurotrashprettyboy This issue isn't related to WebKit. These macOS-native menus that are shown that are created do not offer the capability to have any interaction other than being clicked on. They cannot be right clicked, or dragged. Safari also uses the macOS-native menus, thus also have the same faults. It is completely unrelated to the fact that orion and safari are both based on WebKit.
Chrome and Firefox both chose to implement their own way of displaying menus, which allow for dragging and right clicking on them. It is not related to the fact that they don't use webkit
