Description
Using VS 17.6p3 and working on the compiler project at this commit: https://github.com/jcouv/roslyn/tree/unused-using-bug-67473
I open ExtensionTypeTests.cs and notice a greyed out using directive:

But I remove this using, I get an error on line 5449 which uses VariableDeclaratorSyntax:

I tried investigating whether the compiler is producing an incorrect HDN_UnusedUsingDirective hidden diagnostic, using a command-line build under debugger, but the hidden diagnostic was not produced.
So I suspect there is some IDE issue, possibly with how the compilation is set up.
