Rendering of the form panel of the profiler breaks due to data.id being undefined #29291
Description
Symfony version(s) affected: 3.4.18
Description
The macro form_tree_details and form_tree_entry uses data.id in a lot of places. Some of them check for it to be defined, but some others don't. And I got a case where it fails:
Twig_Error_Runtime:
Neither the property "id" nor one of the methods "id()", "getid()"/"isid()"/"hasid()" or "__call()" exist and have public access in class "Symfony\Component\VarDumper\Cloner\Data".

How to reproduce
I don't have a standalone reproducer for now.
