-----------
REGRESSION (Safari 18.4): Declarative shadow DOM and custom elements do not
work with parseUnsafeHTML
https://bugs.webkit.org/show_bug.cgi?id=292968
rdar://151273154
Reviewed by Chris Dumez.
The regression was caused by the refactoring to support custom element registry
per TreeScope.
When a shadow root is inserted into a document tree with a non-null
custom-element registry,
we should update the associated custom element registry to that of the
destination document
like elements except when the shadow root is specified to use a scoped custom
element registry.
