   This deliberately animates max-height rather than toggling `display`.
   motors-theme-compat.css sets `display: grid !important` on this panel
   (.dealerhub-vehicles-container .dh-filters-grid), and an !important declaration
   in a stylesheet beats the plain inline `display: none` that jQuery's
   slideToggle() writes when its animation finishes. The panel therefore slid shut
   and snapped straight back open on every click. max-height is not contested by
   anything, so collapsing through it sidesteps the fight entirely. */
