Ben Nadel makes the point that pointer-events is another one of those properties that allows you to "undo" what a parent has set. It's like pointer-events just cascades down to descendent elements and you override it, but some properties you just can't come back from, like display above or opacity.
When I got thinking about this I somehow got tinkering with nesting elements and remembered how fun it can be to apply the same animation to lots of nested elements and just see what happens.
