## 12.2.1

### Features
- Undo is document-scoped. An editor adopts the document's existing undo manager and creates one only when the document has none, so several editors over one shared document drive a single stack — an edit made in one editor can be undone from another — and a document keeps its undo history across editor swaps. Behavioral change: the manager is no longer disposed when an editor lets go of a document (its lifetime follows the document), and the `UndoLimit` of an editor that adopts an existing manager does not resize the already-created stack.

### Fixes
- Switching the editor to another document clears the previous document's selection highlight. The new document starts with an empty selection, but nothing repainted the highlight layer until the next selection change, so the rectangles drawn for the old selection stayed on screen over unrelated text until the first click.
- Pointing the editor at another document no longer strips the formatting of the document it lets go of. Releasing a document severed every element from its node, and the next read rebuilt those elements at default formatting - bold, sizes and colours were gone from the elements, from any view still showing the document, and from everything saved or cloned afterwards. It hit any master/detail app that binds one editor to a list of documents, with or without a second view. The editor now suppresses the inherited-property notifications that leaving its logical tree produces (which is all the teardown ever needed to prevent) and leaves the document's element graph intact.
- Two editors (or an editor and a viewer) can bind the same document without fighting over its logical parent: the first host to bind claims it, later hosts attach without claiming, and teardown is symmetric — a non-owning editor letting go of a shared document no longer clears the element references the owning host is still using.
