fix(cdk/drag-drop): preview not inheriting styles inside shadow dom - #21107
Merged
Conversation
By default we create a drag preview by cloning the element and inserting the preview at the document root to avoid issues with `overflow: hidden`. The problem is that the clone won't look correctly if the host styles were encapsulated to the shadow DOM. These changes make it so that we insert the preview at the closest shadow root if the host is inside the shadow DOM, otherwise we fall back to the `body`.
