Steps to reproduce:
1. Open any project
2. Open Package Manager (Window -> Package Manager)
3. In the "Packages:" dropdown select "Packages: My Assets"
4. Select an asset that has a down arrow icon next to it indicating that it can be downloaded
5. Click "Download" button on that asset

Expected result: The icon on the right side of the asset bar changes to a folder since the asset has been downloaded
