A short connection blip no longer flashes Reconnecting or NotSent
A connection blip that recovers in under a second shows nothing, a message that never left is sent again, and the raw NotSent code never reaches the screen.
The window talks to the engine over one link. When that link blinked, the header could flash Reconnecting… and a message could fail with the bare code NotSent.
Now a blip that recovers within the grace period shows nothing. A message that never reached the engine is sent again once the link is back, and if the link stays down you see one plain notice instead of a code.
