page.colocated_path breaks when page.path is set

[opeik]

Bug Report

For some reason, page.colocated_path evaluates to the path as if page.path wasn't set.

Here's the relevant page:

+++
title = "wtf-8"
path = "wtf-8"
+++

{{ figure(src="foo.png") }}

And the relevant shortcode:

{% if src %}
  {# If the image's URL is internal to the site... #}
  {% if src is not starting_with("http") %}
    {# ... then prepend the site's base URL to the image's URL. #}
    {% set src = get_url(path=page.colocated_path ~ src) %}
  {% endif %}
<figure class="{% if position %}{{ position }}{% else -%} center {%- endif %}">
  <img src="{{ src | safe }}" decoding="async" loading="lazy" />
</figure>
{% endif %}

Environment

Zola version: 0.19.2

Expected Behavior

Image URLs on this page evaluate to: {base_url}/wtf-8/{src}.

Current Behavior

Image URLs on this page evaluate to: {base_url}/pages/wtf-8/{src}.
