Styles are not removed after transition slide end

[Addeuz]

Describe the bug

Sometimes the styles applied inline are not removed after the transition is finished. Causing the container that did the transition to have a overflow: hidden (and other things) as an inline style. But then it can work fine 4 tries after.

But the big issue for us is that the overflow: hidden property is there. So any expandable container inside the container doesn't work. As shown in the demo

Reproduction

I was not able to reproduce it locally. But it happens in our staging and production environment, so I've recorded a video. Where one can see that the inline styles are sometimes not removed after the transition finishes. And sometimes they are.
