The bug

When creating a new installation/editing an existing one, attempting to close the installation icon menu while the version selector dropdown menu is also open will only result in the version selector dropdown menu being closed, and the icon menu will remain open.

This is inconsistent with doing the opposite: When attempting to open the installation icon menu while the version selector dropdown menu is open, the version selector dropdown menu will properly close and the installation icon menu will properly open.

How to reproduce

1. Open the Minecraft Launcher, and navigate to the Installations tab
2. Click the New... button in the top left corner
3. Open the icon selector menu
4. Scroll down, and open the version selector menu
5. Scroll back up, and attempt to close the version selector menu
   Notice how the version selector menu closes, but the installation icon menu remains open
