From docs/plans/material-3-browser-tests.md § Actions: submenu
keyboard (Right/Enter/Space open, Left/Escape close and return
focus) and hover-open on a fine pointer; a filtering menu's typing,
arrows, Enter and the clear on reopen; a sheet-at-compact menu's
focus on its first item below 600px, its trigger switching between
menu and dialog across 600px, a submenu opening in place inside it,
its own filter, and a Livewire render keeping it open with the
field's focus; a long menu scrolling while the keyboard keeps the
reached item inside view; the FAB menu's list scrolling on a short
window behind its close button, which stays put (plan step 36,
actions). Written on the data-md-* hooks the group's five commits
render; not run — the group's Chromium pass happens once every
stream in the group has landed.
