New tab sponsored image cached on back usage within certain time

Use case: often opening a new tab, glancing at the sponsored image and directly loading a new page.
Sometimes my interest was delayed and I want to view the image or advertisement again. Hitting the back button or another new tab will be a refreshed page with either no or another sponsored image.

Feature request: hitting back after loading a page from a new tab, within a certain time period (30 - 60 seconds), will display the same (sponsored) image from the new tab page.
