The menu component provides a drop-down/pop-up or embedded menu,

complete with standard menu items, checkbox menu items, radio menu

items, and separators.
Menu items may contain icons and keyboard shortcuts bound to those

items.
All parts of the menu are built with accessibility in mind, making it

usable by people interacting with assistive technologies like screen

readers.
Much of the implementation was built based on the experiences building

the original menu implementation in Review Board and in the

reviewboard.org website, with enhancements to enable crafting, keyboard

shortcuts, checkbox/radio items, embedded mode, and to fix interaction

issues.

Tested the menu in embedded and drop-down modes.
Tested that keyboard shortcuts are registered and work.
Tested light and dark modes.
Unit tests pass.
