When a child element inside an annotation div (e.g. the delete button)
was clicked, the AnnotationLayer's pointerdown handler would call
setPointerCapture, preventing the child's click event from firing.
Using closest('[data-annotation]') instead of checking dataset.annotation
on the target directly fixes delete buttons inside annotation elements.
