[Bug Bash] The tooltip of ‘Package source’ dropdown box in PMC is inconsistent with the PM UI

[CiciLi1]

NuGet Product Used

Visual Studio Package Manager Console

Product Version

NuGet Client Dev\6.12.0.18

Worked before?

It is not a regression since it reproes on D16.11\34601.136 and D17.10\34902.84.

Impact

It bothers me. A fix would be nice

Repro Steps & Context

Repro Steps:   

1. Create a C# Console App (.NET core) project in VS.

2. Click menu Tools->NuGet Package Manager->Package Manager Console to open PMC.

3. Hover on ‘Package source’ drop down list on the left-top of PMC window.

Expected:   

The tooltip should show the selected package source, it should be consistent with the tooltip of the same dropdown box in the PM UI shown below.

Actual:

The tooltip doesn’t show any tip for the selected package source as the screenshot below:

Note:    

1. The repro rate is 100%.

I was able to reproduce. I also noticed that on the initial load of the PM UI the dropdown tooltip is the name of the window that's open.

Once I open and close the source drop down I get the correct tooltip.
