Offset in <g:paginate> is sometimes incorrectly calculated

If we have like 12 displayed elements, and we display <g:paginate> with max=7 offset=5, paginate will display 'next' button, which will point to offset=12, which results in empty list. In fact, playing with max and offset we can trigger paginate to display 'next' button showing well over the total.
The expected behaviour is to never have 'next' button showing to offset greater/equal total.
