Completing record selectors with RecordDotSyntax inserts invalid imports instead

[evertedsphere]

In a record selector (.foo.|) (with | indicating the cursor), if there is a bar completion indicating a .bar field declared in Bar that would be valid there, HLS will treat this as a qualified import of bar and insert something like

import Bar as foo

f = (.foo.bar|)

which is syntactically invalid. I would expect the same completion but without the invalid import.

Although not ideal, a quick fix for this within HLS could be for the "add import" feature to simply warn/error on syntactically invalid requests.

I can reproduce the issue with the following Haskell source file:

{-# LANGUAGE OverloadedRecordDot #-}

module MyLib where

data Foo = Foo
    { bar :: Int
    , foo :: Int
    , baz :: Int
    }

bazoo foo = foo.|
             -- ^ cursor is here
