Function reparse_with_options 

pub fn reparse_with_options(
    old_root: &SyntaxNode,
    old_text: &str,
    old_diags: &[ParseDiagnostic],
    edit: &Edit,
    options: &ParseOptions,
) -> Option<Reparsed>

reparse with the ParseOptions the old tree was parsed under. A tree parsed via parse_with_options must be reparsed with the same options, or the correctness invariant (reparse output ≡ full parse of the edited text) breaks for roxygen blocks resolving their markdown mode from the default.
