Description
Steps to reproduce
Minimum working example:
module A where
newtype Foo = Foo Int
module B where
import A (Foo)
f :: Foo
f = Foo 1
Expected behaviour
Data constructor Foo in f = Foo 1 is correctly underlined with red as 'Foo' constructor is not in scope. Clicking ctrl+. opens code actions tab. I would expect to find there action "Add Foo(Foo) to the import list of A." that would append to type import also constructor import.
Actual behaviour
Only available code action is "Add Foo to the import list of A.". This action doesn't change the import.
If the constructor name is different from the type name the code action shows properly and works as expected (that is action "Add Foo(MakeFoo) to the import list of A" shows up and works).
The problem also exist if we use data instead of newtype.

Your environment
I am sorry but I can't find haskell-language-server executable to tell its version. It's not in the path; not in $HOME in .vscode-server, .cabal, .stack, .local; not on Windows in %APPDATA%\Code\User\globalStorage.
I can only say that I expect it to be recent as VSCode updated hls around a week or two ago.
Which OS do you use:
Windows Subsystem for Linux with Ubuntu 20.04.
Which lsp-client do you use:
VS Code
