Hello,
First of all, thanks a lot for all your work on the plugin.
I have an issue with multi-line signatures (as formatted by Brittany).
The rendering of types in lines 2..n of the signature is not consistent with line 1 (it looks like constructors rather than types).
See, eg,

vs (expected)

This could possibly be linked to #1.
Nb: I have seen also #27.
I am using:
- VSC 1.24.1
- Haskell Syntax 2.5.0 (but in the Changelog in VSC I see 3.0.0)
- Haskell Language Server 0.0.19
- HIE 0.2.0.0
