title: Keep a space or nulled button for Wordpress prev_text or next_text when at the start/end of pagination?
body: <p>I'm using the_posts_pagination for simple CPT archive pagination.</p>
  <p>When I'm at the start or end of the pagination, I need to keep the Next/Previous button spacing, but the code removes it automatically.
  The reason is I'm centering the pagination and when the Prev or Next buttons go away the pagination isnt' centered.</p>
  <p>Is there a way to either keep the spacing (and show just a blank area for the button) or to have the Prev/Next buttons stay there, but get unclickable?</p>
  <p>Here's my pagination code:</p>
  <pre><code>&lt;?php the_posts_pagination([
     &quot;mid_size&quot; =&gt; 2,
     &quot;prev_text&quot; =&gt; __(&quot;Previous&quot;, &quot;textdomain&quot;,),
     &quot;next_text&quot; =&gt; __(&quot;Next&quot;,&quot;textdomain&quot;,),
     ]); ?&gt;
  </code></pre>
