Explorer does not refresh when previously removed root is coming back

Testing #133753 macOS. I have a VS Code window open to the `vscode` repo but it does NOT have focus. I instead have focus on another window of VS Code (or another app... same behavior) Here's the script I'm running outside of VS Code: All it does is renames the vscode folder that I have open in VS Code and renames it back 100 times. ```ps 1..100 | % { mv ./vscode ./vscode-olddd sleep 10 mv ./vscode-olddd ./vscode sleep 10 } ``` I noticed that the _removal_ of the vscode folder gets reflected in the VS Code instance with the `vscode` repo (where it gives you the `!` that says this folder doesnt exist) However, when the rename gets changed _back_ to `vscode` thus "recreating" the `vscode` folder, nothing is reflected in the VS Code instance with the `vscode` repo. However, once I focus the VS Code instance with the `vscode` repo then the contents are refreshed and it shows up and everything is fine.
