//! Explicit head RCDATA/RAWTEXT ancestry from the existing owned lexer tape.
//!
//! Title/style text never enters body insertion rules. Slashed starts refuse:
//! the current lexer ends its special-text state on that slash, whereas an
//! HTML parser ignores the slash and continues reading the element's text.
