Ah, at first I was going to suggest changing iconSelector to remove .type-icon-' + icon child selector, to avoid accessing parent node, but I see why it's needed to ensure that each icon has its own event bound. The alternative might be to bind a single event handler to the .switch-block__block button and determine at the time of click which icon type it contains. But this seems to work well and is a much more direct change 👍

function switchBlockType( event ) {
if ( ! selectedBlock ) {
