CompletionItemSelectionBehavior for LINQ methods

[denisbredikhin]

Version Used: 2.7.0

Steps to Reproduce:

1. Call CompletionService.GetCompletionsAsync for following code: string.Format(s
2. Call CompletionService.GetCompletionsAsync for following code: new[] { 1 }.Where(s
3. Compare SelectionBehavior of all items in these two cases

Expected Behavior:
I expect that in first case SelectionBehavior at least for some items would be HardSelection (or Default?) and in second case - SoftSelection, because in VS if I press space after s in frist case - it commits selected value from auto-complete dropdown, while in second case not.

Actual Behavior:
SelectionBehavior is default for all items.

Do I wrongly understand meaning of SelectionBehavior? If yes, can you suggest me which flag do I need to check to have the same behavior in my code editor as in VS?
