Accordion close animation not staying shut

Hey folks, under the FAQ section (“Got more questions?”) on this page, I’m having trouble getting the closing animation finished.

the faq-close interaction is applied to the faqs wrap class on the accordion, but when the accordion is shut the rich-text in each item shrinks and then expands again in its closed state.

Any help here is much appreciated.
