+Previously, the background styling behind code snippets in AI in-chat responses did not fully cover the entire snippet area. Portions of the code appeared without proper background coverage, reducing readability and creating an inconsistent visual presentation in the AI chat interface.
+
+In {productname} {release-version}, the background styling for code snippets in AI in-chat responses has been corrected to fully cover the entire snippet area. Code snippets now display with complete and consistent background coverage, improving readability and visual consistency.
