Setting hidden attribute on a context menu item does not apply on the first open

I'm seeing an issue where nothing in the context menus Add section can be hidden on the first time the menu is opened. After the first time it works as expected

Steps to reproduce:
Add this code

    features : {
        taskContextMenu : {
            processItems({ taskRecord, items }) {
              items.add.menu.items.addTaskAbove.hidden = true
            }
        }
    },

Open a context menu

It should hide addTaskAbove but you should see that the menu item is only hidden after the menu has been opened a second time. This was run in firefox on one of the demos if it makes a difference.
