Testing Notes

1. In the Espresso theme, make sure that the Create menu and More Options (3 dot) menus flyouts all look as expected:

2. Switch to the Snow theme, make sure that a drop shadow appears beneath menus and hovering over a menu item shows both text and icon in a light color. The theme can be changed on-the-fly or remotely by entering this command in the browser console:
   openmct.install(openmct.plugins.Snow())

This fix is verified during testathon 08/04/2022. Border and drop shadow styling is present for context menus in the MCT tree, three dot menu, and inspector time bounds overlays.
