... which is just a bug in the Org fontification code.
If you try M-: (org-element-at-point) <RET>, you will see that Org does
recognize the code block.

So ...

Org already recognizes nested blocks using Org element parser. See
https://orgmode.org/worg/dev/org-element-api.html

See https://list.orgmode.org/87ee7c9quk.fsf@localhost/
This is something we are working in.
To get parser-aware fontification locally, you can use a function
MATCHER (as in font-lock-keywords docstring) and invoke
`org-element-at-point' there to check context.

May you elaborate? `org-element-map' iterates through everything,
including nested parent and child blocks. What did you try?

Sorry, but it is hard to see how this is related to `org-element-map'.
