Research direction

Reproduce the paren-matching behavior in DrRacket 8.17 on macOS using a small program with matching parentheses; no source file or test is named in the issue. Find the DrRacket editor implementation responsible for paren matching, then verify that placing the cursor next to a parenthesis highlights the enclosed text.
