"Disable BB Code Within This BB Code" not working?
 

(I'm using vBulletin 3.8.4* Patch Level 1.)

I've created a custom BB Code* "python"* which is supposed to expand to Code:
[highlight=Python]{param}[/highlight]
and then be parsed into a code block in the post.

This highlighting is done with a Product* and works perfectly when I enter the expanded tags manually into the window. For example* entering:
Code:
[highlight=Python]import sys[/highlight]
is properly outputted as a code block* but entering:
Code:
[python]import sys[/python]
is outputted as the plain text with naked BB Code:
Code:
[highlight=Python]import sys[/highlight]
and not as a code block.

Now* my first thought was that I had accidentally disabled BB Code within custom BB codes* but this is not the case -- I've set it to "No." I've also tried the same thing with the bold tag* and it outputs the naked BB Code there as well* instead of boldface text. I've attached the settings for this custom BB Code.

Am I missing something obvious? I've reached my wits' end.

Thanks!
