 &lt;p&gt;Did I roll my own modal at first? Regretfully, yes. I&#39;d used the &lt;code&gt;&amp;lt;dialog&amp;gt;&lt;/code&gt; element before... several years ago... in a project I don&#39;t have access to anymore... Needless to say, I had forgotten about its existence.&lt;/p&gt;
 &lt;p&gt;Anyway, I got there. Eventually. So let&#39;s talk about modals and &lt;code&gt;&amp;lt;dialog&amp;gt;&lt;/code&gt;.&lt;/p&gt;

 &lt;p&gt;Do not add the &lt;code&gt;tabindex&lt;/code&gt; property to the &lt;code&gt;&amp;lt;dialog&amp;gt;&lt;/code&gt; element as it is not interactive and does not receive focus.&lt;/p&gt;

 &lt;p&gt;despite this, I found that in Firefox (but not Edge), the &lt;em&gt;&lt;code&gt;&amp;lt;dialog&amp;gt;&lt;/code&gt; itself was focusable&lt;/em&gt;. I have no idea why, but I tested this on a totally unstyled and unmodified page and still found it to be true. As a focusable element, it made no sense. It had no interactivity and could not be activated.&lt;/p&gt;
 &lt;p&gt;I&#39;m still torn: do I add &lt;code&gt;tabindex=&amp;quot;-1&amp;quot;&lt;/code&gt;? MDN specifically says not to, but I&#39;m pretty sure they&#39;re warning against making it &lt;em&gt;focusable&lt;/em&gt;. Why warn against making it nonfocusable when &lt;em&gt;it&#39;s not supposed to be focusable in the first place&lt;/em&gt;, after all?&lt;/p&gt;
 &lt;p&gt;At current, I&#39;m ambivalent, but I&#39;ve added &lt;code&gt;tabindex=&amp;quot;-1&amp;quot;&lt;/code&gt; to handle Firefox&#39;s poor behavior. Making the dialog focusable is unhelpful and confusing.&lt;/p&gt;
