Re: [csswg-drafts] [css-values-4] Add new relative length units that are relative to the size of the system cursor (#8315)

> the developer should know the characteristics of the cursor they are adding

Even if authors know the size of the image they are providing, the final cursor may be scaled:

> If an operating system is incapable of rendering a cursor above a given size, cursors larger than that size must be shrunk to within the OS-supported size bounds

Also, different elements can have different cursors, and even if they have the same size, they may have different `<x> <y>`. So knowing which values to use in the tooltip would require knowing the style of the hovered element.
