Seems like the total count is based on the results prior to folding. (As folding happens after query time)
It would be nice to adjust the total count so it could remain constant while navigating through result pages.
The index returns the total count, but when you navigate through the pages, folding reorganize the results in clusters, which reduce/increase the total result. JS UI should be able to adjust/counter this behavior.
