 * The panel is max-height animated from 0 to its measured scrollHeight
 * on open, then the inline max-height is removed so content can reflow
 * on resize. The `max-height: none` override on .is-open matches the
 * lesson learned in the Expand Cards plugin (v1.0.2 there): without it,
 * the CSS default (0) snaps back in when JS removes the inline style
 * and the panel auto-collapses.
