When typing out a Razor directive (like `@renderrmode`) completely, you get snippet completions instead of C# completions

[danroth27]

If I fully type out @rendermode at the top of a .razor file (without using the completion), when I hit the space I get snippet completions instead of C#, which means you don't get completions for the actual render mode values:

Repro steps:

• Create a new Blazor Web App
• In Home.razor at the top of the file try to type out @rendermode including the trailing space

Expected result: Completions for the render mode values are offered
Actual result: Snippet completions are offered
