bug#62400: 30.0.50; csharp-mode syntax highlight problem

[牟 桐]

Hi, I noticed that in `csharp-mode`, code like this will not be
highlighted correctly:

``` csharp-mode
using Stream stream
             |
             ^
           plain
```

The first character of `stream` is not highlighted.

Looks like this is a duplicate of bug#62399 (same cause).

Does csharp-mode​ use tree-sitter​ too?

The bug#62399 is caused by the tree-sitter-chsharp​, I thought csharp-mode​ is based on regexp.

My bad, I didn't notice that it was for a different major mode.

I'm copying in the csharp-mode maintainer Jostein Kjønigsen.
