(treesit-node-at (point) 'bash)
=> #<treesit-node (heredoc_body) in 12-56>
I forgot to say that point is before "text2", outside of the
command_substitution node.

tee << EOF
text1 $var
text2 $(echo cmd)
text3
$var2
EOF
Filling a test buffer with these contents and placing point before
"text2", we get
(treesit-node-at (point) 'bash)
=> #<treesit-node (heredoc_body) in 12-56>
(treesit-node-children (treesit-node-at (point) 'bash))
=> (#<treesit-node (simple_expansion) in 18-22>
#<treesit-node (command_substitution) in 29-40>
#<treesit-node (simple_expansion) in 47-52>)
This is now expected.
(point)
=> 23
(treesit-node-first-child-for-pos (treesit-node-at (point) 'bash) (point))
=> nil
This is not expected. One would expect this to return
command_substitution node, since it follows the position 23.
