Describe the issue:
Currently, "Contextual Menu" doesn't close when we use 'tab' key. You can check the behavior here- https://codepen.io/prakhar241/pen/dyOZrpZ.
If you check W3C recommendations on Application Menus • Menus • WAI Web Accessibility Tutorials (w3.org) - this recommends 'tab' to close the menu and select next focus-able element. I think we should concur with recommended practice.
Actual behavior:
tab loops into menu items.
Expected behavior:
tab should close the menu, and focus should stay on closed menu, or point to next focusable item.
