+        `listsinceblock` did not behave correctly when handed a block that was
+        no longer in the main chain:
+
+             ab0
+          /       \
+        aa1 [tx0]   bb1
+         |           |

+                     |
+                    bb4
+
+        Consider a client that has only seen block `aa3` above. It asks the node
+        to `listsinceblock aa3`. But at some point prior the main chain switched
+        to the bb chain.
+
+        Previously: listsinceblock would find height=4 for block aa3 and compare
+        this to height=5 for the tip of the chain (bb4). It would then return
+        results restricted to bb3-bb4.
+
+        Now: listsinceblock finds the fork at ab0 and returns results in the
+        range bb1-bb4.
+
+        This test only checks that [tx0] is present.
