Pull request overview
Fixes DataGrid pager’s displayed page index when switching the page size to “all” (internally pageSize = 0) while virtual scrolling is enabled, ensuring the pager info shows a valid “Page 1 of 1 …” state.
Changes:
- Adjust pager page index calculation to handle
pageSize === 0(the “all items” mode). - Add a TestCafe e2e regression test covering the virtual-scrolling + pageSize “all” scenario.

This function is used to get visible index of the current page, that is passed to pager so it could display it.
If in pager the pageSize 'all' is selected, then dataController.pageSize() == 0, and so there's only one page.
