<h3 id=dimension-attributes>Dimension attributes</h3>

This section details monkeypatches to [[!HTML]]'s <a href="https://html.spec.whatwg.org/multipage/embedded-content-other.html#dimension-attributes">Dimension attributes</a> section. This section will be updated to include <{fencedframe}> in the list of elements that the <code>[=width=]</code> and <code>[=height=]</code> dimension attributes apply to.

<h3 id=new-request-destination>New fencedframe [=request=] [=request/destination=]</h3>

Every distinct element should have its own request destination to allow for special handling when making requests (fenced frame request behavior deviates from iframe behavior in enough ways to justify having a separate destination). Update the associated request [=request/destination=] list to include a new entry, "<code>fencedframe</code>". It will have the [=request/initiator=] "", the CSP directive <code>fenced-frame-src</code>, and the features HTML's <code>&lt;fencedframe&gt;</code>.

Add "<code>fencedframe</code>" to the [=non-subresource request=] list and to the [=navigation request=] list.

Add "<code>fencedframe</code>" to the {{RequestDestination}} enum.

In the [=fetch=] algorithm, step 13.2, where it says:

> A user agent should set value to the first matching statement, if any, switching on request’s [=request/destination=]:

Add "<code>fencedframe</code>" to the switch cases alongside "<code>document</code>", "<code>frame</code>", and "<code>iframe</code>".

Modify it to say

> If origin is <a>same origin</a> with response's <a for=response>URL</a>'s <a for=url>origin</a>, and [=request/destination=] is not "<code>fencedframe</code>", then return <b>allowed</b>.
