Strange output for NormalizeWhitespace for `1 is var i`

[svick]

Version Used: 4.7.0

Steps to Reproduce:

Run the following code:

SyntaxFactory.ParseExpression("1 is var i").NormalizeWhitespace().ToString()

Expected Behavior:

The code returns the string "1 is var i", i.e. it returns the code unchanged.

Actual Behavior:

The code returns "1is var i", i.e. there is no space between 1 and is. This is technically correct C#, but I find this formatting quite odd and not consistent with how is is formatted in other cases.
