Reproduction steps:
1. Create a new project
2. Window > Package Management > Package Manager
3. Install any Asset that displays “Locate” and “Manage” buttons in Package Manager after being installed (e.g. “Asset Store UPM Publishing Tools”)
4. Press “Manage” button and select “Customize” option
Actual result: “Locate” and “Manage” buttons disappear and “Install” button reappears
Expected result: “Locate” and “Manage” buttons remain
Reproducible with: 6000.3.0a3, 6000.3.3f1, 6000.4.0b3, 6000.5.0a4
Couldn’t reproduce on: 6000.0.65f1, 6000.3.0a2 (No “Manage” button after installing the Asset)
