This was a regression made visible by the recent change to
enforce dimensions on this overlay, which in turn visualizes
the blocked/unblocked states of the preview (see fc6d6ffad)
Partially reverts "fixes" from 411673ed. This re-introduces the arrow on the main tree node in the CMS ("Your site name"), but that's less important than being able to navigate tree hierarchies in the first place in TreeDropdownField.
In certain cases, the button may not yet be initialized or may no longer have button properties at the time of removal from the DOM. Without this check, an uncaught exception is thrown.
Also removing the 'changed' class from the form once
no further fields are marked as changed. That's important
now that we're surfacing the state much more visibly
through the alternative "save" button styles in the CMS.
Title in CMS is set using header X-Title. But UTF-8 characters can't be used in HTTP headers. So the title should be encoded just before sending X-Title header and decoded before setting HTML document title (fixes#7942).
Specifically, the change removed the "add page" panel padding,
because it moved padding from .cms-panel-padded into
commonly contained elements, like .ui-tabs-panel.
Apart from breaking layouts, it makes the class meaningless,
since its only padded depending on which elements it contains.
In order to rectify some introduced inconsistencies,
much too complex were required, e.g.
.ui-tabs .cms-edit-form, .ui-tabs .cms-content-fields {...}.
Was originally added for CMS grouped actions,
but can't see any effect. Probably related to the unreleased
changes around the new "batch actions" and "add page" panel styling.
It breaks button height in the top toolbar, by shifting from jQuery
UI's (well tested) mode of applying padding to the container,
to applying padding to the contained text instead. This
conflicts with the line-height set on many buttons.
The new 'liszt:ready' handler is called late enough to trigger the
update, whereas the redraw is called to early for IE8 to pick up the
class change. The class property is changed correcly though, it looks
like an IE8 rendering issue.

Move onresize handler from entwine to regular event for IE8. The
fromWindow::onresize does not trigger otherwise.

Introduces the concept of action tabsets - usage of TabSet and Tabs
in between the action buttons to allow richer set of capabilities that
can be offered to the user.
Goes along with c8d0cdec99c95dbed3b58ebcc098cc9d22c58206 that implements
a change to the CMS actions.
Backport from master. Fixes display issues with expanded,
unselected submenus ... by removing them.
They're strictly not necessary since both "list" and "add"
modes can be reached through the default AssetAdmin UI.
