     <p><code><a href=http://www.whatwg.org/specs/web-apps/current-work/#attr-contenteditable>contenteditable</a></code> content attribute does not define a new <a href=#undo-scope>undo scope</a>
     and all <a href=http://www.whatwg.org/specs/web-apps/current-work/multipage/editing.html#editing-host>editing hosts</a> share the same <code><a href=#undomanager>UndoManager</a></code> by default.
-    And the <code><a href=#attr-undoscope>undoscope</a></code> content attribute on an <a href=http://www.whatwg.org/specs/web-apps/current-work/multipage/editing.html#editable>editable</a> element is ignored.</p>
+    And the <code><a href=#attr-undoscope>undoscope</a></code> content attribute on an <a href=http://www.whatwg.org/specs/web-apps/current-work/multipage/editing.html#editable>editable</a> element is ignored
+    except on <a href=http://www.whatwg.org/specs/web-apps/current-work/multipage/editing.html#editing-host>editing hosts</a>.</p>
 
-    <p>When the <code><a href=http://www.whatwg.org/specs/web-apps/current-work/multipage/editing.html#contenteditable>contenteditable</a></code> content attribute is added to an element,
-    the user agent must remove all entries in the <a href=#undo-transaction-history>undo transaction histories</a> of the editable <a href=#undo-scope>undo scope hosts</a> that are descendent of the element
-    and have become <a href=http://www.whatwg.org/specs/web-apps/current-work/multipage/editing.html#editable>editable</a> without <a href=#dom-transaction-unapply>unapplying</a> or <a href=#dom-transaction-reapply>reapplying</a> the entries

-    <p>Conversely, when the <code><a href=http://www.whatwg.org/specs/web-apps/current-work/multipage/editing.html#contenteditable>contenteditable</a></code> content attribute is removed from an element,
-    the user agent must define new <a href=#undo-scope>undo scope</a> for each descendent element with the <code><a href=#attr-undoscope>undoscope</a></code> content attribute
-    and create a new <code><a href=#undomanager>UndoManager</a></code> to manage any <a href=#dom-changes>DOM changes</a> made to descendents of each element,
-    excluding <a href=#undo-scope-host>undo scope hosts</a> and their descendents, as if the <code><a href=#attr-undoscope>undoscope</a></code> content attribute was re-added to descendent elements with
