Iterable text fields are displayed incorrectly in flex-object list view

[vangogs]

Iterable text fields are displayed incorrectly in flex-object list view:
e.g.:
["Value1","Value2"]

Iterable text fields in flex-object list view are rendered from template
[templates/forms/fields/text/edit_list.html.twig]

There are bug in statement introduced in commit
{% set value = iterable ? value|join(', ') : value|string %}

As per my understanding value is iterable ? must be used instead of iterable ? because there are no iterable variable in twig context

To make it work, I am using following statement:
{% set value = (value is iterable) ? value|map(item=>item|string)|join(', ') : value|string %}
