Nodes appear pretty-printed like this:
#<treesit-node
(block)
in 159-173>
Because `pp-buffer' uses `downward-list' and `upward-list' to
determine list boundaries and where to line break.
The solution is to perhaps consider using a different notation than
`(block)' in the printed representation of the object. (Or make
`pp-buffer' much smarter, but that is perhaps far more work.)

I see, and I guess using parenthesizes inside an object could break other things.
Although I like the correspondence between query syntax and printed node
type [1], it’s probably better not print parenthesizes inside an object.
Now that node is printed as #<treesit-node block in 159-173>
[1] (block) -> #<treesit-node (block) in ...>
";" -> #<treesit-node ";" in ...>
