comma breaks parser

[rafipiccolo]

when i add this comma before the last ")" twig breaks and renders nothing. white page.
twig php does support this comma.

{% set motifs = motifs|merge(
    [
        {id: 'blabla'},
    ], {# <====  this comma is the issue #}
) %}

The comma gets added because of a linting rule that i apparently can't disable.
VincentLanglet/Twig-CS-Fixer#328

is there any chance of this to be supported ?

There are some issues with multi-line arrays/maps that could also be causing this.
