msbuild restore followed by a msbuild RestoreLockedMode=true always fails

I would expect the following to always succeed.

msbuild test.sln /t:restore
msbuild test.sln /t:restore /p:RestoreLockedMode=true

On my machine it always fails with:
error NU1004: The packages lock file is inconsistent with the project dependencies so restore can't be run in locked mode. Please disable RestoreLockedMode MSBuild property or pass explicit --force-evaluate flag to run restore to update the lock file.

Steps to reproduce

$nugetconfig = @"
<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageSources>
    <add key="nuget" value="https://api.nuget.org/v3/index.json" />
  </packageSources>
</configuration>
"@

$dirprops = @"
<Project>
  <PropertyGroup>
    <!--NUGET RESTORE SETTINGS -->
    <RestorePackagesWithLockFile>true</RestorePackagesWithLockFile>
    <!--NUGET RESTORE SETTINGS -->
  </PropertyGroup>
</Project>
"@

mkdir test
cd test
mkdir ".nuget"
$nugetconfig | Out-File ".nuget\nuget.config"

$dirprops | Out-File "Directory.Build.props"

dotnet new sln
mkdir Fabric.Classlib
mkdir Fabric.Base.ClassLib
cd Fabric.Classlib
dotnet new classlib
cd ..
cd Fabric.Base.Classlib
dotnet new classlib
cd ..
cd Fabric.Classlib
dotnet add reference ..\Fabric.Base.Classlib\Fabric.Base.Classlib.csproj
cd ..
dotnet sln add Fabric.Base.Classlib\Fabric.Base.Classlib.csproj
dotnet sln add Fabric.Classlib\Fabric.Classlib.csproj
msbuild test.sln /t:restore
msbuild test.sln /t:restore /p:RestoreLockedMode=true

Expected behavior

msbuild test.sln /t:restore /p:RestoreLockedMode=true should succeed.

Actual behavior

Fails with the below error.

error NU1004: The packages lock file is inconsistent with the project dependencies so restore can't be run in locked mode. Please disable RestoreLockedMode MSBuild property or pass explicit --force-evaluate flag to run restore to update the lock file. [C:\Temp\test\test\test.sln]

Thanks. This is a duplicate of #8187. It's already fixed and should be released in preview3 soon.
