Accordion missing transition

[sergeydus]

When opening/closing an component, there is supposed to be a transition animation

example:

this is a fork from the tailwind accordion page, for some reason it works fine on the website, but on blitzstack it the transition doesn't work, (locally doesn't work aswell)

version: 4.0.5
