SQL code inspection when editing function/procedure DDL

When I work on procedure DDL (via database tool window) sql code inspections do not work, but when I work in the query console or php file where there is sql code they work fine. For example:

Is this a bug or is there any option to enable code inspection also when working directly on DDL?

I will be grateful for any help.
