[UI] Editor hover window size is strange

[xiaohai-huang]

Type: Bug

1. Create a C# file
2. Create a class with a very long summary
3. Hover the mouse over the class name

/// <summary>
/// Arthur raises his sword and leaps towards an enemy hero, dealing 16/20/24% magic damage to the enemy hero's maximum health and knocking them up for 0.5 seconds. 
/// At the same time, he summons a holy seal to cover the landing area. 
/// The holy seal deals 85/105/125 points of magic damage per second to enemies within range for 5 seconds.
/// </summary>
public class Test
{

}

Actucal Result

The text in the hover window does not wrap properly and cannot see the whole summary.

Expected Result

The hover window should show all the text and wrap automatically like what it does in JavaScript file.

I try to create a hover using the markdown provided by the C# LSP Logs.

  vscode.languages.registerHoverProvider("csharp", {
    provideHover(document, position, token) {
      return new vscode.Hover(
        "```csharp\r\nvoid AbilityThreeAction.OnUpdate()\r\n```\r\n  \r\nArthur summons 3 shields that circle around him, enemies that are struck by the shield will receive 145/163/181/199/217/235 \\(\\+80% physical bonus\\) Physical Damage\\. Shields last for 5 seconds\\.  \r\n"
      );
    },
  });
