Start by reproducing the win32 Windows Terminal failure described by the Feedback ID, then trace the VirtualMessageList stack through the reported B:/~BUN/root/chunk-j41eq7es.js and chunk-cg0jytez.js locations. Done means the itemKeys/messages length desync no longer occurs for the reported scenario and the error is no longer emitted.
