Build fails when properties are in platform-conditional PropertyGroups

[xXTurnerLP]

What happened?

When I open the ASM Viewer window it fails to compile the project and looking into the "show details" button it says dotnet failed to compile due to CSC : error SYSLIB1062: LibraryImportAttribute requires unsafe code. Project must be updated with '<AllowUnsafeBlocks>true</AllowUnsafeBlocks>', however the project already does have AllowUnsafeBlocks in the csproj and can be build perfectly fine with Rider

Relevant log output or stack trace

Steps to reproduce

I found that the issue triggers when you have the <AllowUnsafeBlocks>true</AllowUnsafeBlocks> placed in the configuration specific blocks in the csproj, if you place the AllowUnsafeBlocks attribute in the root one where it has no filters it will work properly

This triggers the issue:

<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug|x64' ">
    <AllowUnsafeBlocks>true</AllowUnsafeBlocks>
</PropertyGroup>

<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Release|x64' ">
    <AllowUnsafeBlocks>true</AllowUnsafeBlocks>
</PropertyGroup>

If you put it in the main one, it will work and build properly:

<PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net10.0</TargetFramework>
    <LangVersion>latest</LangVersion>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>disable</Nullable>
    <Configurations>Release;Debug</Configurations>
    <Platforms>x64</Platforms>
    <AllowUnsafeBlocks>true</AllowUnsafeBlocks>
</PropertyGroup>
