Splitting generic type parameters over multiple lines sometimes puts the break in an invalid place

[Smaug123]

Issue created from fantomas-online

Code

namespace Foo

type Bar =
    member Hello : thing : LongLongLongLongLongLongLongLong<bool -> 'a, bool -> 'b, bool -> 'c, bool -> 'd, bool -> ('e -> 'f) -> 'g, ('h -> 'i) -> 'j> * item : int list -> LongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLong

Result

namespace Foo

type Bar =
    member Hello :
        thing : LongLongLongLongLongLongLongLong<bool -> 'a, bool -> 'b, bool -> 'c, bool -> 'd, bool
            -> ('e -> 'f)
            -> 'g, ('h -> 'i) -> 'j>
        * item : int list ->
        LongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLong

Problem description

Had to contort myself a lot to get this one! The line break isn't in a valid place for some reason, due to offside rules.
