This patch is a final major refactor in styling Angular. This PR includes three main fixes: All temporary state taht is persisted between template style/class application and style/class application in host bindings is now removed. Removes the styling() and stylingApply() instructions. Introduces a "direct apply" mode that is used apply prop-based style/class in the event that there are no map-based bindings as well as property collisions. PR Close #32259 PR Close #32591
