would lead to <tt>UnsupportedOperationException</tt>

<p>This returns the window that is the representative of the added window after adding.
This can either be the new window itself, if no merge occurred, or the newly merged
window. Adding an element to a window or calling trigger functions should only
happen on the returned representative. This way, we never have to deal with a new window
that is immediately swallowed up by another window.

contain the new window as part of the list of merged windows.
@param newWindow The new {@code Window} to add.
@param mergeFunction The callback to be invoked in case a merge occurs.
@return The {@code Window} that new new {@code Window} ended up in. This can also be the
