Unable to sort related records by fieldname

[peterboorsma]

I'm trying to order a list of related records by a number field (mode: float), like this:

{% set relatedrecords = record|related('songs') %}
{% for related in relatedrecords|order('tracknumber') %}
<p>{{ related.tracknumber }}, {{ related|title }}</p>
{% endfor %}

My contenttype field:

        tracknumber:
            type: number
            mode: float

But my list of records does not follow the ordering I want.

There is a dirty workaround for those who need it quickly, like moi :)

{% set relatedrecords = record|related('songs')|sort((a,b) => a.tracknumber <=> b.tracknumber) %}
{% for related in relatedrecords %}
...
{% endfor %}
