Example Reddit social share URL interpolates relative URL rather than encoded absolute URL

[tlindsay42]

Description

The custom Reddit social sharing link example on the Layouts page of the documentation specifies to populate the url parameter with {{ page.url | relative_url }}, which fails to populate the URL field in the popup window when implemented. If the interpolation syntax is replaced with the encoded absolute value: {{ page.url | absolute_url | url_encode }}, as implemented in the theme default social-share.html file, the URL field will populate properly in the popup window.

<a href="https://www.reddit.com/submit?url={{ page.url | relative_url }}&title={{ page.title }}" class="btn" title="{{ site.data.ui-text[site.locale].share_on_label }} Reddit"><i class="fab fa-fw fa-reddit" aria-hidden="true"></i><span> Reddit</span></a>

Environment

Expected behavior

The URL field should be populated with the page URL in the share on Reddit popup window.

Steps to reproduce the behavior

1. Create an override social-share.html file and populate it with the code found here page of the documentation.

<a href="https://www.reddit.com/submit?url={{ page.url | relative_url }}&title={{ page.title }}" class="btn" title="{{ site.data.ui-text[site.locale].share_on_label }} Reddit">
  <i class="fab fa-fw fa-reddit" aria-hidden="true"></i><span> Reddit</span>
</a>

1. Serve the site
2. Navigate to a page with sharing enabled, and click on the Reddit link and the URL will not be populated.
