/**
 * The label has to be the flex row, not the span inside it.
 *
 * `.bw-pf__option-inner` is `display: flex`, which makes it a *block-level* flex
 * container. Left as the only flex box, it forces a line break after the input
 * and the text drops onto the line below the control. Promoting the label to the
 * flex row puts the input and the text on one line, with the count still pushed
 * right by `.bw-pf__option-label`'s flex-grow.
 *
 * Scoped to these two display types: swatches and buttons visually hide the
 * input and rely on `.bw-pf__option-inner` being the sized box.
