Explorer does not collapse after closing file preview

[septatrix]

Issue Type: Bug

1. Create a new directory and open VSCode in it.
2. Create a file in a subdirectory which you can open in preview mode.
   • A simple method would be to type npm i foobar in the console, create a main.js file with the content import "foobar"; and then use the "Go to Definition" feature.
3. See that the directory structure in the explorer got expanded to show where the file is.
4. Close the file preview.
5. See that the treeview still is expanded.

This is especially annoying when working with large dependency structures like pythons .venv or nodes node_modules. After looking up some implementation details the whole explorer view is filled and one has to scroll down or collapse the respective directories to be able to see the usual project files.
