Reviewed the selection-wrapping behavior against the linked issue and existing markdown editor insertion conventions. The change correctly wraps a non-empty selection with backticks, preserves the inner selection, and avoids intercepting modified key combinations. No blocking issues found.

@cwh please review

Reviewed the requested selection-wrapping behavior and the caret-position follow-up. Pressing an unmodified backtick with a non-empty selection wraps the selected text, leaves modified shortcuts untouched, moves the caret after the closing delimiter, and emits the editor input event. The JavaScript also passes node --check; no blocking concerns found.
