method steps are:

<li><p>Let <var>global</var> be <a>this</a>'s <a>relevant global object</a>.

<li><p>Let <var>origin</var> be <a>this</a>'s <a>relevant settings object</a>'s

<a for="environment settings object">origin</a>.

<!-- Arguably this should snapshot origin somehow so that changes to it do not impact the

in parallel part. -->

<li><p>Let <var>promise</var> be <a for=/>a new promise</a> in <var>global</var>'s

<a for="global object">Realm</a>.

<li><p>Let <var>permission</var> be <a>permission</a> for <var>origin</var>.

<li><p>If <var>permission</var> is "<code>default</code>", then ask the user whether showing

notifications for <var>origin</var> is acceptable. If it is, then set <var>permission</var> to

"<code>granted</code>"; otherwise "<code>denied</code>".

<p><a>Queue a global task</a> on the <a>DOM manipulation task source</a> given <var>global</var>

to run these steps:

<li><p>Set <a>permission</a> for <var>origin</var> to <var>permission</var>.

<li><p>If <var>deprecatedCallback</var> is given, then <a for=/>invoke</a>

<var>deprecatedCallback</var> with « <var>permission</var> ». If this throws an exception, then

<a>report the exception</a>.

<li><p><a for=/>Resolve</a> <var>promise</var> with <var>permission</var>.

<p>The <dfn method for=ServiceWorkerRegistration><code>showNotification(title, options)</code></dfn>

method steps are:

<li><p>Let <var>global</var> be <a>this</a>'s <a>relevant global object</a>

<li><p>Let <var>promise</var> be <a>a new promise</a> in <var>global</var>'s

<a for="global object">Realm</a>.

<li><p>If <a>this</a>'s <a for="service worker registration">active worker</a> is null, then

<a for=/>reject</a> <var>promise</var> with a {{TypeError}} and return <var>promise</var>.

<!-- We might have to throw directly here and below, see

https://github.com/web-platform-tests/wpt/pull/24601 -->

<li><p>Let <var>serviceWorkerRegistration</var> be <a>this</a>.

<li><p>Let <var>notification</var> be the result of <a>creating a notification</a> given

<var>title</var>, <var>options</var>, and <var>serviceWorkerRegistration</var>. If this threw an

exception, then <a for=/>reject</a> <var>promise</var> with that exception and return

<var>promise</var>.

<li>

<p>Run these steps <a>in parallel</a>:

<li><p>If <a>permission</a> for <var>notification</var>'s <a for=notification>origin</a> is not

"<code>granted</code>", then <a>queue a global task</a> on the

<a>DOM manipulation task source</a> given <var>global</var> to <a for=/>reject</a>

<var>promise</var> with a {{TypeError}}, and abort these steps.

<li><p>Run the <a>fetch steps</a> for <var>notification</var>.

<li><p>Run the <a>show steps</a> for <var>notification</var>.

<li><p><a>Queue a global task</a> on the <a>DOM manipulation task source</a> given

<var>global</var> to <a for=/>resolve</a> <var>promise</var> with undefined.

<li><p>Return <var>promise</var>.

method steps are:

<li><p>Let <var>global</var> be <a>this</a>'s <a>relevant global object</a>.

<li><p>Let <var>realm</var> be <var>global</var>'s <a for="global object">Realm</a>.

<li><p>Let <var>origin</var> be <a>this</a>'s <a>relevant settings object</a>'s

<a for="environment settings object">origin</a>.

<!-- Arguably this should snapshot origin somehow so that changes to it do not impact the

<li><p>Let <var>promise</var> be <a for=/>a new promise</a> in <var>realm</var>.

<li>

<p>Run these steps <a>in parallel</a>:

<li><p>Let <var>tag</var> be <var>filter</var>'s <code>tag</code>.

<li><p>Let <var>notifications</var> be a <a for=/>list</a> of all <a>notifications</a> in the
