Incorrect links in pagination bar [5.2.1-RC1]

Below each grid In-Portal displays a pagination bar. Typical pagination bar looks like this:

[<<] [<] 7 8 9 10 11 12 13 14 15 16 [>] [>>]

Here is the meaning of each symbol:

[<<] - would change current page to "current_page minus 10" (10 - displayed page count)
[<] - would change current page to "current_page minus 1" (goes to previous page)
7 - 16 - page numbers
10 - page number, that is currently active
[>>] - would change current page to "current_page plus 10" (10 - displayed page count)
[>] - would change current page to "current_page plus 1" (goes to next page)

Usually [<<] and [>>] links are not displayed, because of small record count or large per-page setting in the grids.

Recently I've noticed however, that, when used on Front-End these [<<] and [>>] links are pointing to incorrect page numbers.
