Subject: [PATCH] Update "actualPages" immediately

Instead of immediately updating the value once the page count changed, it got updated after "pagesToSpreadState" changed, which was after the rendering finished.

This was the actual root cause of what was tried to be fixed with 9ab6ec89c7c0f7d346190a7ad6fd27efcd898ca1
