[Bug Bash] The last selected version in the filtered dropdown list will not show correctly in ‘Version’ dropdown box after typing a part of the version

NuGet Product Used

Visual Studio Package Management UI

Product Version

VS Main\11128.256 + NuGet Client Dev\7.1.0.43

Worked before?

It is not a regression since it reproes on 17.14.17 with NuGet 6.14.1.1.

Impact

It bothers me. A fix would be nice

Repro Steps & Context

Notes:

1. The repro rate is 100%.
2. It just happens when selecting the last version in ‘Version’ dropdown list, doesn’t repro when selecting other versions.

Repro Steps:

1.Create a C# Console App (.NET 10.0) in VS.
2.Right-Click the project in the Solution Explorer window and select ‘Manage NuGet Packages…’.
3.Select the source “nuget.org” in the “Package source:” drop-down list and go to “Browse” tab.
4.Click a package (e.g. ‘NUnit’) and type a part of a valid version (e.g. 3.13) in the "Version" drop-down box on the right panel.
5.Click the arrow-down button and select the last version at the bottom of the dropdown list.

Expected Result:

The last selected version (in this instance is ‘3.13.0’) should show successfully in the ‘Version’ dropdown box.

Actual Result:

The last selected version will not show correctly in ‘Version’ dropdown box as the screenshot below.

3.13 is a valid representation of version 3.13.0, maybe because the user selected a specific version of the list we need to change the text, I think we are doing a version comparison instead of a string comparison here

Team Triage: If we use Moq as an example, the last version is 3.1.416.3. If we type 3.1 in the version box and then click on the 3.1.416.3 option, the text in the Version box still only shows 3.1 which is not equivalent to 3.1.416.3:

After clicking on last item in dropdown:

However, notice that clicking on the last item in the dropdown does in fact select that version 3.1.416.3 as is shown in the Package Details. We can even click Install and it works. But the text in the Version box is not updated to reflect the chosen version.
