How to deselect all elements across all pages on serverside table?

Link to test case: This can be seen in the serverside table example

Description of problem:
I have noticed that when some elements are selected on page 1, then we go on page 2 and select other elements, Deselect All (selectNone) only deselects the elements on the current page, and those on the other pages remain selected.
How can I clear the selection across the entire table?

Thank you!
