ctrl-enter (insert line below, insert line above) in middle of line not adding `///`

When having
```cs
/// <summary>
/// Hello| world
/// </summary>
```

pressing ctrl-enter or ctrl-shift-enter (Insert line below, insert line above) at the indicated location will insert a new line but not insert any `///`.

With insert line below it will enter it if the cursor was at the very right, with insert line above it seems like it never inserts it.
