You have all the wrong places, this is all valid functionality.

You want this place:

dlls/gdi/metafile.c::PlayMetaFileRecord
...
    case META_ESCAPE:
	Escape(hdc, mr->rdParm[0], mr->rdParm[1], (LPCSTR)&mr->rdParm[2], NULL);
	break;
...

This call should use a whitelist of the valid GDI Escapes in metafiles.

Ciao, Marcus
