Buffers now hold on to all tags from both this window and the last window of items instead of just this window.
This protects against the rare times when one block is called twice before another block is, thereby pruning the tags before they can be passed downstream. The same thing will happen if a block is called 3 times in a row, which is highly unlikely.
