... because of missing TD tags in global Preferences layout

The global layout in Confluence 2.6.0 is missing a <td> tag in Preferences, causing the border underneath the tabs not to be rendered. To fix this, need to add the following <td> tags in the default global layout:

#elseif ($context == "profile")
#set ($readOnly = $helper.action.user && $userAccessor.isReadOnly($helper.action.user))
<td valign="top"> <!-- ADDED HERE -->
<ul class="tabnav">
<li class="tabs">
#foreach ($item in $action.webInterfaceManager.getDisplayableItems("system.profile", $action.remoteUser, $helper))
<a href="$item.link.getDisplayableUrl($req, $helper)" #if ($mode == $item.key) class="current"#end>$item.label.getDisplayableLabel($req, $helper)</a>
#end
</li>
<li class="spaceActionLinks">
#if ($action.space)
#personalSpaceLink()
#else
#createPersonalSpaceLink()
#end
</li>
</ul>
<!-- clears the floated elements above -->
<br class="after-tabnav">
</td> <!-- ADDED HERE -->
</tr>
