<p>Removing the <code data-x="attr-dialog-open">open</code> attribute will usually hide the
dialog. However, doing so has a number of strange additional consequences:

<ul>
<li><p>The <code data-x="event-close">close</code> event will not be fired.</p></li>
<p>The following <span data-x="concept-element-attributes-change-ext">attribute change
steps</span>, given <var>element</var>, <var>localName</var>, <var>oldValue</var>,
<var>value</var>, and <var>namespace</var> are used for <code>dialog</code> elements:</p>

<li><p>The <code data-x="dom-dialog-close">close()</code> method, and any <span data-x="close
request">close requests</span>, will no longer be able to close the dialog.</p></li>
<ol>
<li><p>If <var>namespace</var> is not null, then return.</p></li>

<li><p>If the dialog was shown using its <code data-x="dom-dialog-showModal">showModal()</code>
method, the <code>Document</code> will still be <span data-x="blocked by a modal
dialog">blocked</span>.</p></li>
</ul>
<li><p>If <var>localName</var> is not <code data-x="attr-dialog-open">open</code>, then
return.</p></li>

<p>For these reasons, it is generally better to never remove the <code
data-x="attr-dialog-open">open</code> attribute manually. Instead, use the <code
data-x="dom-dialog-close">close()</code> method to close the dialog, or the <code
data-x="attr-hidden">hidden</code> attribute to hide it.</p>

This won't work, because it will return in step 1, because the open attribute has already been removed.

I guess we need to factor out steps 3-9 into a separate algorithm. Maybe "process open attribute removal"?

Whoops I forgot that, I added a parameter to close in chromium. I just added it here. What do you think?

I think it's slightly harder to understand than factoring out the steps would be, but I don't feel too strongly. (Thanks for updating the algorithm declaration style while you were there!)

<li><p>Hiding a dialog is different from closing one. Closing a dialog gives it a return value,
