Space before should not be introduced for index expression

[nojaf]

Issue created from fantomas-online

Code

type Foo() =
    member _.Bar () = dict [ "a", "a" ]

let key = "a"
let fooo = Foo()
fooo.Bar()[key]

Result

type Foo() =
    member _.Bar() = dict [ "a", "a" ]

let key = "a"
let fooo = Foo ()
fooo.Bar ()[key]

Problem description

Produces warning FS3369: The syntax 'expr1[expr2]' is ambiguous when used as an argument. See https://aka.ms/fsharp-index-notation. If you intend indexing or slicing then you must use 'expr1.[expr2]' in argument position. If calling a function with multiple curried arguments, add a space between them, e.g. 'someFunction expr1 [expr2]'.

Extra information
