Razor highlighting lost after a multiline member definition in @code block.

## Issue Description ##
In a razor file, in a @code block, syntax higlighting is lost after certain multiline property definitions.

## Steps to Reproduce ##
Create a razor file:
```

@code {
[Parameter]
public string Param1 { get; set; }
[Parameter]
public string Param2 { get; set; }
[Parameter]
public string Param3 { get; set; }
[Parameter]
public string Param4 { get; set; }
}
```
Add a linebreak before "Param2".

## Expected Behavior ##
Syntax highlighting remains intact.

## Actual Behavior ##
Syntax highlighting is gone from the linebreak onward.

Before and after:

It seems like it reverts back to html syntax highlighting in this case. Notice how the following html element is correctly highlighted.
