Note the "ERROR" nodes in the syntax tree, and the failure to highlight "Hello" as a string.

Thanks for this!

You'll need to repoen this one against https://github.com/zed-extensions/haskell, as we cannot fix this within Zed itself.

Semantic highlighting sadly does not seem to be supported for HLS yet, see haskell/haskell-language-server#4672
