ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — This PR adds a substantial new keyboard, focus, submenu, and screen-reader behavior model to production web context menus, changing existing interaction paths. An unresolved Medium-severity focus-management issue further indicates that the new interaction state needs human review. Not approved because:

The new submenu test enters only with ArrowRight. The fake DOM dispatches keydown events but does not model native button activation, so a regression in Enter or Space activation can pass these tests. Cover both keys through

The web app's in-page context menu could only be operated with a mouse. Focus now moves into the menu when it opens; Up/Down, Home/End move between enabled items, Right/Left enter and leave submenus, Escape closes one level and Tab dismisses the menu. The menu and items expose menu/menuitem roles. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
The highlight relied on focus events, which browsers skip when focus moves while the window lacks focus, so arrow keys moved focus without highlighting. It now follows the focused item and an open submenu's trigger. Holding an arrow also smeared the highlight through a color transition and let a resting pointer steal focus as the menu scrolled under it; the transition is gone, hover is ignored until the pointer moves, and the focused item scrolls into view. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Snooze presets now carry their time as a separate `detail` so screen readers announce "In 1 hour, 3:00 PM" instead of reading the parentheses; native desktop menus still show "In 1 hour (3:00 PM)". Submenus are named after their trigger, menu icons are hidden from assistive tech, and the first item takes focus when a menu opens. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Hovering the parent menu's padding removed a submenu that held focus, leaving focus on the page and the arrow keys dead until another item was hovered. Closing submenus now returns focus to their trigger whichever way they close. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

Sorry, I'm unable to act on this request because you do not have permissions within this repository. |

Note This comment is posted by Julius' dot The after screenshot and keyboard recording show the improved menu, but the PR explicitly omits the before evidence. The verification rule requires a before/after comparison for these visible and interactive changes. I'm closing this pending that evidence. Add a matching before screenshot and a short baseline recording showing the failed keyboard interaction, then request reconsideration. |

@juliusmarminge I added the missing before/after comparisons, you can reconsider! :) |

Problem
The web fallback context menu (thread rows, sidebar, etc.) can't be used from the keyboard: arrow keys, Home/End, Escape, and submenus do nothing, and there is no visible focus. Screen readers also read the snooze presets with their literal parentheses ("In 1 hour, parenthesis, 3:00 PM, parenthesis"), submenus have no name, and decorative icons are exposed.
This PR was made to improve accessibility in view of adding a setting to choose between native and web right-click menus. That setting would make the web menu the everyday menu for desktop users who pick it, so it has to be keyboard and screen reader friendly first.
Change
contextMenuFallback.ts): follows the WAI-ARIA menu pattern. Arrow Up/Down wrap between enabled items, Home/End jump, ArrowRight/Enter/Space open a submenu and focus its first item, ArrowLeft/Escape close one level, Tab closes everything and returns focus to the element that opened the menu. Shift+F10 / the context-menu key open it.ContextMenuItemgains an optionaldetailfield (contracts). Snooze presets use it for the time. The web menu shows it as muted trailing text and labels the item "In 1 hour, 3:00 PM". Native Electron menus keep rendering "In 1 hour (3:00 PM)". Submenus getaria-labelfrom their trigger, icons arearia-hidden, and the first item takes focus on open. After a right-click it's focused without a highlight; after a keyboard open it's highlighted.Scope and approval
No prior issue. This is a focused bug fix limited to the existing fallback context menu: it was not keyboard operable, which is an obvious accessibility defect. The only cross-package change is the optional
detailfield, needed so the snooze time can be read naturally without changing how native menus look. (Added bonus of looking better)Before:
