VSCode extensions view will always show on restart

[sgraband]

Bug Description:

The closed/open state of VSCode extension views is not properly stored. When i close a view and restart the application it will the view will show up again. I was able to reproduce it with at least these three extensions:

• ms-kubernetes-tools.vscode-kubernetes-tools
• github.vscode-github-actions
• ms-azuretools.vscode-docker

Im unsure if this comes from something that is going on inside these extensions, but they work in VSCode. I would assume that just something is off with views that are registered via contributes.views, as all three extensions provide the views like this.

Steps to Reproduce:

1. Install one of the extensions
2. Close the view in the left tab bar
3. Restart the application and notice that the view is there again

Note: Moving the widget works and does not reset, but once its closed it will always come back
