 Fenced frames use an additional reserved navigation target "<code>_unfencedTop</code>" to navigate.
 This section patches the relevant portions of the [[HTML]] spec to add <code>_unfencedTop</code>.
 
-Extend [=valid navigable target name or keyword=] to include a new keyword named <code>_unfencedTop
-</code>.
-
-In the following paragraph, change "top" to refer to the [=navigable/traversable navigable=] of the
-[=navigable=] that the link or script is in. Add an additional clause to the same sentence that
-reads: "outermost top" is the [=top-level traversable=] of the [=navigable=] that the link or
-script is in.
-
-Note: This change is necessary because this spec adds a distinction between [=navigable/traversable
-navigable=] and [=top-level traversable=], which were previously functionally equivalent.
-
-In the table below, add a column named "Effect in a fenced frame". The value for all rows in
-this column is the same as "ordinary effect". Then, add two rows which read:
-
-<table>
-  <thead>
-    <tr>
-      <th rowspan=2>Keyword</th>
-      <th rowspan=2>Ordinary effect</th>
-      <th colspan=2>Effect in an <code>iframe</code> with...</th>
-      <th rowspan=2>Effect in a fenced frame</th>
-    </tr>
-    <tr>          
-      <th><code data-x="">sandbox=""</code></th>
-      <th><code data-x="">sandbox="allow-top-navigation"</code></th>
-    </tr>
-  </thead>
-
-  <tbody>
-    <tr>
-      <td><code>_unfencedTop</code> if outermost top is current</td>
-      <td>current</td>
-      <td>current</td>
-      <td>current</td>
-      <td>current</td>
-    </tr>
-    <tr>
-      <td><code>_unfencedTop</code> if outermost top is not current</td>
-      <td>outermost top</td>
-      <td>none</td>
-      <td>outermost top</td>
-      <td>outermost top</td>
-    </tr>
-  </tbody>
-</table>
-
-Add an extra step to [=the rules for choosing a navigable=] between the current steps 6 and 7, that
-reads:
-
-6.5. Otherwise, if name is an ASCII case-insensitive match for "_unfencedTop" and 
-|currentNavigable|'s [=navigable/traversable navigable=] is a [=fenced navigable container/fenced
-navigable=], set <var ignore=''>chosen</var> to |currentNavigable|'s [=top-level traversable=].
