Bug report

Reproduction of the problem

Dojo example.

1. Hide the second row.
2. Slowly scroll the Spreadsheet horizontally (left and right).

Current behavior

Column lines disappear and row lines appear (columns G, M, N, O). In Chrome values disappear as well, observe the value in column F. The configuration options required for reproducing the behavior are mergedCells and frozenRows.

Expected/desired behavior

No changes to the column/row lines and no disappearing values on scrolling.
