bq. I only doubt the filter based scan
There is a chance that the top cell will be changed if the filter return
NEXT_ROW or SEEK_NEXT_USING_HINT.
TestStore#testFlushBeforeCompletingScanWithFilter and
TestStore#testFlushBeforeCompletingScanWithFilterHint reproduce the bug.

> If we use the cell which won't be flushed into disk as the top cell to reopen
> the scanners, the new top cell will change. If the new top cell is in
> different row, the matcher will reset, and then matcher will accept the new
> top cell...
