-// This test verifies a real bug I hit developing the vector-of-sequences
-// approach to resuming events. A small omission caused the event IDs in a
-// resumed stream to _omit_ channels that were in the original stream until
-// those channels also appeared in the resumed stream.
-//
-// Clients would see something like
-// * In the original stream, Cfoo=5,Cbar=8
-// * In the resumed stream, Cfoo=6 (no Cbar sequence number)
-//
-// Disconnecting and reconnecting a second time, using event IDs from that
-// initial period of the first resume attempt, would then cause the second
-// resume attempt to restart all other channels from the beginning, and not
-// from where the first disconnection happened.
-//
-// This is a real and valid behaviour for clients!
