TYPO3 Core

I've got some page content, and it contains two separate hyperlinks which are separated by a space. The space appears just fine in the backend rich text editor, but it disappears when the content is rendered on the frontend. The content element is a Regular Text Element provided by Typo3 core.

I have attached screenshots of how things appear in the backend and the frontend. The issue appears between the words "user" and "uses" towards the end of the English sentence.

Below can be found the content source code as it appears first in the backend rich text editor, and second in the browser. The issue reproduces consistently across different pages on my site, but I have not experimented beyond that, and won't do so unless other people are unable to reproduce.

Backend rich text editor source:

<p>An <strong>user purpose</strong> of a <a href="t3://page?uid=9">tool</a> is a <a href="t3://page?uid=14">purpose</a> for which an <a href="t3://page?uid=11">user</a> <a href="t3://page?uid=20">uses</a> the tool.</p>

Frontend rendered HTML:

<div id="c17" class="frame frame-default frame-type-text frame-layout-0"><p>An <strong>user purpose</strong> of a <a href="/field/documentary-field/tool">tool</a> is a <a href="/field/documentary-field/tool/purpose">purpose</a> for which an <a href="/field/documentary-field/tool/user">user</a><a href="/field/documentary-field/tool/usage">uses</a> the tool.</p></div>
