GNOME Shell Extension Alt+Tab Scroll Workaround

Quick fix to the bug where scrolling in one application is repeated in another when switching between them using Alt+Tab (e.g., VS Code and Chrome)

As an example, after scrolling VS Code and switching to Chrome using Alt+Tab or Super+Tab, the VS Code scroll would be repeated in Chrome. Installing the extension should avoid this.
