com.google.android.packageinstaller causes bootloop on Xiaomi 11T

**Your phone**: Xiaomi 11T

**Describe the issue**
Uninstalling `com.google.android.packageinstaller` seems to work at first (it shows as uninstalled in the list), but upon reboot, it's always back.

Tried disabling it via Settings>Clear and `disable packages instead of uninstalling them`, and that caused a bootloop (this was the only package I have disabled in this particular reboot attempt, so I know it's this one).

The issue is about a specific package causing a bootloop on a Xiaomi device. Research how the tool handles package uninstallation/disablement, particularly for system packages like com.google.android.packageinstaller. Look at the ADB command logic and the GUI code that manages package states. Check if there are existing tests for package removal on different device models. Understanding Android system package persistence and Xiaomi's MIUI behavior is key to diagnosing the bootloop.
