A security and an accessibility review of the proofreading hook found gaps, fixed here. What leaves the browser: - A checker gets a name for each composer of its own, not the composer's id, so it can't reach the message through the other api.composer calls after proofreading stops. - Checking pauses while a plugin that can sign or encrypt is turned on but still starting, and while the policy couldn't be fetched (the built-in defaults could undo an admin's lock). - No plugin can hold up turning proofreading off (onBeforeSettingChange). - Suggestions can't carry zero-width, bidi or line-separator characters; messages lose bidi overrides; a flood of annotations is cut off early. - The notices name the plugin as installed, not a label it chose, and say that text written before signing or encryption was turned on may already have been checked. - A checker registered during start-up no longer fails its first check. Keyboard and screen readers: - Escape in the issue panel closes the panel, not the message. - Underlines carry aria-invalid, as the browser's own markers do. - The focus goes somewhere sensible when a button or an issue goes away, Tab past the popup's edges goes back to the text, and the shortcuts work in the popup and the panel. - Ctrl+' and Ctrl+; follow the character typed, so other layouts keep their own keys (Ctrl+S on Dvorak), with Ä and Ö on German keyboards. - The popup is described by its message, sits inside a modal composer, fits narrow screens, and the panel fits a phone.
