It's nothing to do with "capture phase", it's to do with CSS inheritance. The
'pointer-events' property is inherited, and therefore if a parent has
pointer-events="none" the children will inherit this value unless they override it.

Note that pointer-events only helps decide if an element is the _target_ of an
event, and therefore which element an event is targeted at. It does not stop
handlers on an element from being triggered if an event has been dispatched to
one of that element's children (because the child overrode pointer-events).
