iOS: ArrangeTests edge-flip test is flaky #161

testHoldingAtTheEdgeFlipsToTheNextPageAndDropsThere failed once on PR #160 and passed on rerun; recent main runs show no failures. Afterward auto-merge didn't fire until it was re-armed. Watch for a repeat before fixing; if it fails again, look at how the edge-hold timer is awaited in the test.
