Parent cannot be changed from Inline editing mode

Reproduced with such scenario:
1. Create a parent and a child page with some object for which sheet allows inline editing by default.
2. Delete parent. Child will still have deleted page as parent, shown in breadcrumb.
3. Enter default (Inline) editing mode and try to change parent page to existing one.
Expected result: parent reset, breadcrumb is updated.
Actual results: old deleted page stays the parent.
Workaround: works ok from WYSIWYG editing mode.

Probably this is reproduced not only for deleted pages, but simply for Inline editing mode.
