What is the current behavior?
With previous versions of Stencil where we didn't not had support for DSD, we used to comment selectors and transform them so that shadow components can by hydrated as scoped components. To have the styles applied properly, we would transform them and keep the original selector commented, e.g.:
GitHub Issue Number: fixes #5880
Since component styles are handled at compile time there is no easy way for us to just render define this behavior when calling
renderToString. Hence this PR will change the behavior of how shadow components are being serialized. It now doesn't render the shadow DOM anymore if theserializeShadowRootis set to false. Before Stencil would transform a shadow component into a scoped component. This behavior will be removed with this patch.To keep Stencil somewhat backwards compatible, I switched the default value for
serializeShadowRoottotrue.What is the new behavior?
CSS style text is not transformed into scoped styles anymore, nor there is any selector commenting.
