Excessive key presses caused Exception: System.InvalidOperationException: Cannot locate the offset in the rendered text that was pointed by the original cursor

Start with the exception path through RecomputeInitialCoords, ReallyRender, ForceRender, and Insert, using the reported key sequence and buffer dimensions as the investigation context. Determine a reproducible input or rendering state, then verify that equivalent excessive key presses complete without the InvalidOperationException.
