I think you can remove this |ChangeSelection| line, same in the longpress test.

Hmm, why reset? It should be a simple matter of testing outside the rect, then
inside the rect, no need to reset the selection and establish a new one. I would
remove the HideAndDisallowShowingAutomatically() call here and also the
ChangeSelection call below.

+  controller().HideAndDisallowShowingAutomatically();
+
+  // Establish a selection without handles from 5 to 50 with height 10.
+  ChangeSelection(start_rect, visible, end_rect, visible);
+  EXPECT_THAT(GetAndResetEvents(), IsEmpty());
+
+  // A point inside the rect should be handled.
+  EXPECT_TRUE(controller().WillHandleLongPressEvent(inner_point));
+  EXPECT_THAT(GetAndResetEvents(), ElementsAre(SELECTION_SHOWN));
+}
