[Bug Bash] The splitter in the PM UI cannot be dragged after resizing the VS window from the full-screen mode

[v-luzh]

NuGet Product Used

Visual Studio Package Management UI

Product Version

Dev\6.11.0.34

Worked before?

It is a regression since it doesn’t repro on D16.11\34601.136 and D17.9\34601.282.

Impact

It bothers me. A fix would be nice

Repro Steps & Context

Repro Steps:

1. Create a C# Console App (.NET Core 8.0) project in VS.
2. Right-click the project in Solution Explorer and select "Manage NuGet Packages…" menu item to open PM UI.
3. Resize the whole VS window from the default full-screen mode.
4. Drag the splitter in the PM UI to the left or right.

Expected Result:

The splitter in the PM UI can be dragged to left or right.

Actual Result:

The splitter in the PM UI cannot be dragged to left or right as the recording below.

Notes:

1. Repro rate: 100%.
2. It doesn’t repro when the VS window is in full-screen mode by default (at the end of the recording).
3. It also reproes for the splitter of solution-level PM UI.
4. It also reproes for the 'Installed'/'Updates'/'Consolidate' tab.

I repro'd this. I believe it's a regression on my change here. Looking into it.
