If the scrollbar pseudo-elements are used to change the appearance of the scrollbar, live changes to the applicable styles are not applied immediately. Instead, the parts of the scrollbar must be hovered, at which point they will change their appearance.

See the attached testcase for an example. A button is used to toggle a 'dark' class on the document element. Different styles apply to the body and the scrollbar when this class is present, but the new scrollbar styles are not picked up immediately, instead it retains the old appearance until it is hovered.
