Staircase in logger seems not to be properly fixed

[0xced]

I see that commit 2850ac5 from pull request #4756 is part of the v17.9.0-preview-23577-04 tag, yet even after upgrading the Microsoft.NET.Test.Sdk package to version 17.9.0-preview-23577-04 I'm still seeing the staircase issue. 🤔

Reproduction steps are the same as in the original bug report (#4754) with the following command between step 2 and 3:

dotnet add tests/Serilog.Formatting.Log4Net.Tests.csproj package Microsoft.NET.Test.Sdk --version 17.9.0-preview-23577-04

The loggers don't come with the test.sdk package, the fix is propagated with vstest.console update, meaning you need to get it by upgrading your dotnet sdk / Visual Studio / TestPlatform package.

It will come with 8.0.2xx sdk: https://github.com/dotnet/sdk/blob/release/8.0.2xx/eng/Versions.props

I'm not sure in what exact version of the SDK this was fixed but I confirm that the staircases are gone with the dotnet SDK 8.0.204.
