this relates to Beta 22.214.171.124 of Toad for Oracle.
In cases where a query is terminated with a – comment immediately followed by a semicolon on the next line,
any blank lines separating the query from the next one are discarded by the formatter.
Leaving one blank line in place would be nice.
select * from dual
– any comment
select * from dual;
After formatting the blank line is gone.
