How can I document types in a multidimensional array to fix type hinting?

I have some template files that have default arguments defined at the top of each file. I can't get type hinting for these values to work correctly; it just says there is no reference. I am including the WordPress core files in Intelephense, so it understands what a WP_Post is, I just can't get it to understanding typing on a multidimensional aray.


I found this GitHub issue which discusses a similar problem, and includes some suggestions on things to try. No matter which method I used, all I can get it to respond with for $args["post"] is `No references found for 'post'".


Eventually, I found this WordPress forums thread discussing a similar issue, and links to this WordPress core file which includes the "WordPress-y" way to do document multidimensional arrays, but even this still results in the same message.


That's how I've gotten to this point, but this doesn't seem to be working correctly either, because the reference pop-up looks quite odd (screenshot below), and doesn't seem to do anything for type hinting.










Also, I understand that perhaps a class structure would be better, and I will look in to that, but that entails retooling our templating system, so that will take time. For now, I'd like to get type hinting working in this use if at all possible.
