Child Sim stretches when sliding multiple times

When I queue multiple "Slide the Plank" interactions on a jungle gym with a slide, my child Sim stretches weirdly when transitioning from one slide action to another.

I have all the packs, game is on the latest version, tried with a normal Sim child and a fairy child (Mara Summerdream) and the same thing happened. This is in a fresh new save where I have never used mods or CC. I'm on a desktop, Windows 11 Pro.

The slide is on their home lot. I have not tested at a park, but I don't think it would make a difference. No LE generated that I noticed.
