Transition animation doesn't reset after closing/reopening

[kevinkucharczyk]

This can be seen even in the docs: https://ember-basic-dropdown.com/docs/animations/

The transitioning--in etc classes don't get reset after the first render. When the dropdown content first renders, it animates correctly, but on subsequent renders there is no animation - it appears instantly.

Here'a a screencast:

You can see how on the first click in smoothly animates in, but after that it doesn't.

There also doesn't seem to be a transitioning-out animation, even though it's defined in the CSS.

Yes, I am experiencing the same in ember-power-select as it uses this addon under the hood.

Can't find dropdown--transitioning-out in the codebase at all also.

Same problem in this example https://ember-power-select.com/cookbook/css-animations/
