Vue: Nested Transition Not Working

[nkalush]

Version

2.3.3

Reproduction link

https://jsfiddle.net/7xfktcn9/

Steps to reproduce

Try to transition elements inside an element that is transitioned.

What is expected?

The interior elements would use the rules from the closest tag when they are supposed to transition.

What is actually happening?

The interior elements do not transition, they use neither the closest or parent's transition tag's rule.

Might be similar to https://github.com/vuejs/vue/issues/3664, but that is for a much older version of vue and the user provided no jsfiddle and his example code used extra stuff.

You need to add a key attr to the tabs 🙂 https://jsfiddle.net/me0tftdw/
