Interaction open on Size-height snapping to final position

On this page, About Admire Interiors, when clicking on the profile link to to open the profile, the profile is revealed. The action is smooth to start with but there’s a snapping/judder into final position at the end which I can’t make smoother.

The interaction uses the Size-height action. Starts at height:0 then changes to height:auto over .4 seconds. It’s currently using the ‘ease’ easing - I’ve tried linear, ease-out, ease-in-out, none of which make it better.

Any ideas as to how to make this better?

Cheers
Grant
