docfx docfx building in MSBuild does not respect <TreatWarningsAsErrors>property settings

Operating System: Windows

DocFX Version Used: 2.59.3

Template used: default

Steps to Reproduce:

In an existing docfx fle, where docfx issues a warning when built, do the following:

Create sdk style csproj file in same dir as docfx.json file to integrate docfx build in msbuild
add package reference <PackageReference Include="docfx.console" Version="2.59.3" />
Set <TreatWarningsAsErrors>true</TreatWarningsAsErrors>. Project file looks like this:

<?xml version="1.0" encoding="utf-8"?>
<Project Sdk="Microsoft.Build.NoTargets">
  <PropertyGroup>
    <TargetFramework>netstandard2.0</TargetFramework>
    <TreatWarningsAsErrors>true</TreatWarningsAsErrors>
  </PropertyGroup>

  <ItemGroup Label="PackageReferences">
    <PackageReference Include="docfx.console" Version="2.59.3" />
  </ItemGroup>
  
</Project>

Run dotnet restore and dotnet build from the command line

Expected Behavior: The warning is reflected, and the build fails due to the warning +TreatWarningAsError

Actual Behavior: Console shows docfx waning, but msbuild sees no warnings, here is my console output: [...] Build succeeded with warning.
