Visual Studio status bar stuck in "Building" state bug

**Visual Studio Version**:

Microsoft Visual Studio Enterprise 2019
Version 16.9.5
VisualStudio.16.Release/16.9.5+31229.75
Microsoft .NET Framework
Version 4.8.04084

Installed Version: Enterprise

**Summary**:

I found a small bug in Visual Studio, it should be pretty easy to recreate. If you open a _.csproj_, that does not yet belong to a _.sln_ and build. It will prompt you to create/save a new _.sln_ file. However, there is already an in-memory solution that is loaded just not yet persisted to disc. This can cause another dialog, which offers to "Save as", "Overwrite", "Cancel" and something else I can't recall. I choose overwrite, it saved - but remember... I was in the context of a build.

The status bar shows that it's building - but never actually does. The menu options show that build is available, so a build will clear it out. But the status will not update otherwise. Not sure if that's an important one or not

**Expected Behavior**:

The status bar state should have been cleared / reset.

**Actual Behavior**:

The status bar reporting that it was "Building"

**User Impact**:

It was confusing and misleading at first, took me a bit to realize that it wasn't actually building. As the build menu items were again enabled.
