We previously set the selections' z-index: -1 to avoid the selections
blocking click events. However, this doesn't work on block-level
elements, such as image-blocks, because the selection is perfectly
behind the image.
This change removes the z-index assignment, and we instead let the
selections remain on top, but we apply pointer-events: none to avoid
the selections reacting to click or touch events.
