Nathan Nguyen	37f3e607a6	Disconnect template descendants hosted inside Viewbox when the template changes (#21879 ) * Add failing test for template child presented inside Viewbox not being reparented on template change When a ControlTemplate contains Viewbox > ContentPresenter presenting a control that outlives the template, swapping the template throws "The control already has a visual parent" because the old presenter never releases the presented control. Repro for #9551. * Forward TemplatedParent to Viewbox's internal container so template teardown reaches its subtree Viewbox hosts its Child inside an internal ViewboxContainer visual that is a visual child but not a logical child of the Viewbox. Template teardown (TemplatedControl.ApplyTemplate) finds descendants to disconnect via GetTemplateDescendants, a visual-tree walk that stops recursing at any visual whose TemplatedParent is null. ViewboxContainer never had a TemplatedParent, so the walk stopped at it and template descendants hosted inside the Viewbox (e.g. a ContentPresenter) never had their TemplatedParent cleared. Their template bindings therefore stayed live, the old ContentPresenter kept the presented control as its visual child, and re-presenting that control in the new template threw "The control already has a visual parent". Forward the Viewbox's TemplatedParent to the container, restoring the invariant that every template descendant is reachable through visuals whose TemplatedParent is non-null. Null is deliberately not forwarded: teardown clears the Viewbox's TemplatedParent while iterating lazily, and forwarding null would prune the walk before it reaches the container's subtree; the walk clears the container's TemplatedParent itself instead.

Steven Kirk	35db70c8d4	Don't expose viewbox container as logical child. #7735 introduced an internal container control which hosts the child, but it exposed this child in the logical tree, breaking any styles which relied on the `Viewbox.Child` being the logical child of the `Viewbox`. Fix this by introducing a simple internal `ViewboxContainer` control as the container.	4 years ago
