First of all - great and really helpful theme component.
But I think I found a bug. If I use a placeholder in a code snippet, that contains backticks (`), it is not working. An example is a SQL code snippet:
DELETE FROM `=TABLENAME=`
WHERE id NOT IN(
SELECT
id FROM (
SELECT
id FROM `=TABLENAME=`
ORDER BY
id DESC
LIMIT 20
) subquery);
TABLENAME gets never replaced (if there is a TABLENAME placeholder).
