Review comment:
RM commented out line, OR swap the line below it with one that doesn't _
ignore the index. As far as I can read it,
`for i, w := range elm.Windows { ` should be identical and let you remove `w
:= elm.Windows[i]`

> When splitting an element that's being processed on multiple windows,
> currently the element gets split based on the current progress of the current
> element+window pair, and the primary and residual both contain all windows
> from the original. This is incorrect as certain windows in the residual have
> already been processed.
> The correct way to perform this split is to put the element + all fully
> processed windows in the primary, the element + all fully unprocessed windows
> in the residual, and then only split the element at the current element +
> window pair.
> This fix should already be in Java and Python, so those can be referenced.
