Sometimes when editing a node layout you can see the following error in the console:
Uncaught TypeError: this.details.siblings(...).each(...).end().show().siblings(...)[0] is undefined
I've marked this as a bug in Carnation, but it's not 100% clearcut to me. It's possible the core JS could be improved to be less brittle, but I think the fundamental issue is using the attributes variable in the template in an inner container (normally I think it's on the outer) in input.html.twig. That then leads to unexpected markup in the vertical tab for revision information.

Hello @AndyF ,
It seems related to the core issue described there -
https://www.drupal.org/project/drupal/issues/3291764
🐛
The [0] hatch in misc/vertical-tabs.js causes issues if there are multiple forms with vertical tabs.
Needs work
We are planning to include a patch from the issue directly to the distro.
