With this change we save a copy of of scroll state at the time of recording a display list, instead of actual ScrollState pointer that could be modifed by the main thread while display list is beings rasterized on the rendering thread, which leads to a frame painted with inconsistent scroll state. Fixes https://github.com/LadybirdBrowser/ladybird/issues/4288
