Previous cssEscape only handled " and \, leaving NUL/newlines/control chars to break out of the CSS string literal. Port the CSSOM string serialization rules: NUL becomes U+FFFD, control chars become \HEX, quotes/backslashes get escaped. Class selector switched from `.x` (which would need separate identifier escaping) to `[class~="x"]`, which is also semantically correct for multi-class elements.
