If I run emacs 28.2 (with -q) and open the following org file, I can evaluate both source blocks but only the "bash" block has syntax highlighting. I've confirmed that opening a zsh script (e.g. with a zsh shebang) highlights correctly. If this list isn't the right place to ask about this issue, does someone know where I could look for help?

This is the right place to ask.  And thanks for asking!

I'm able to reproduce it.

I'm not familiar with how Org handles the font lock.  However, I notice that calling C-c ' (`org-edit-special') results in the error:  No such language mode: zsh-mode

I suspect that without a language mode, Org has no way to know how to color the block.

As a quick work around, you can define zsh-mode as shell-script-mode to get coloring:

(defalias 'zsh-mode 'shell-script-mode)
