How to configure customized logo

[WeihanLi]

When I tried to use a customized app logo, the svg displayed abnormal, how could I adjust the style or adjust the image aspectio?

docfx config:

{
  "build": {
    "globalMetadata": {
      "_appName": "dotnet-talks",
      "_appTitle": ".NET Talks",
      "_appLogoPath": "images/dotnet-logo.svg",
      "_appFaviconPath": "images/favicon.ico",
      "_enableSearch": true,
      "pdf": false
    }
  }
}

The dotnet-logo.svg is as follow:

<svg width="456" height="456" viewBox="0 0 456 456" fill="none" xmlns="http://www.w3.org/2000/svg">
