2. Rezise the browser so that only 2 rows and 2 columns are visible
3. Open about:telemetry in a new tab ans go to Histograms section
4. Filter after "newtab"
5. Open another about:newtab page and refresh the about:telemetry page
5. Check the NEWTAB_PAGE_DIRECTORY_LINKx_SHOWN data

Expected results:
NEWTAB_PAGE_DIRECTORY_LINKx_SHOWN has the data only for the tiles in view

Actual results:
NEWTAB_PAGE_DIRECTORY_LINKx_SHOWN has the same value for the tiles in view:

NEWTAB_PAGE_DIRECTORY_LINK8_SHOWN
2 samples, average = 8, sum = 16
