F9 with -- Comments in 13.1.1.5 gives ORA-00933

I have always used the new line to separate statements that I want to execute using F9. This is no longer working if I use comments

Select * from Table1
-- To Recreate use F9 on statement above with this comment underneath

Select * from Table2
-- I get ORA-00933

Thanks, I can reproduce and will log.
