I noticed that the second item in my accordion stopped working properly. The content expands, but the icon does not change and the element attributes like the class name .brx-open are not applied to the correct element.
If I clone the first item that does work properly (which has the same structure in Bricks) it works again.
I managed to resolve it by deleting the affected accordion item and duplicating a working one (or adding a fresh one). Unfortunately therefore I don’t have a link I can share with you.
