Tiling background image does not loop when scrolling until redraw (e.g., by resizing) #2409

Summary

A tiling background does not loop past the initial viewport region when you scroll until you force a redraw by resizing the window or similar.

Operating system

Linux

Steps to reproduce

Put a small background image on a body with a tall height, enough so you can scroll. (Please see provided reduced test case.)

Expected behavior

Background image should continue seamlessly looping when you scroll.

Actual behavior

When you scroll past the initial viewport region, Ladybird then shows only the background color, instead of the background image continuing to tile, until it fully redraws.
