Review of the pop-out work found ways to lose text, a wrong sign-out and changes reaching ordinary browser tabs. - Drafts: a closing window hands text over only to a main window holding its login, and asks instead when the last save failed, the browser is offline, a save is running or plugins could still have a say. A failed rescue goes to "Continue draft". The opening window lets go only once the composer is on screen, also for Edit draft in a message window. Send options travel with the draft. Closing during a send asks first. - Sessions: answers are encrypted for the window that asked, and only a window holding the login answers. A renewal queued on the lock can be called off by a sign-out, signs nobody out once its account is gone, and takes the cached token after waiting (Rauthy `nbf`, #552). - Ordinary tabs run none of the host. No lock is held for life. - A message window hides after a refused session and waits for its folders; a composer stays on screen with its text. Another tab dropping a login it couldn't restore no longer closes pop-outs. - Plain-text mail stays selectable in the desktop app. Folder save renames reserved and shell names and skips one refused name. All display-mode checks know the overlay. The attachment bar keeps to one row. The earlier test that accepted text being gone after a failed rescue now asserts that it reaches the "Continue draft" slot.
