Uninstalling com.google.android.webview breaks K-9 Mail

**Xiaomi Redmi Note 4 (MediaTek)**: \

**Describe the issue**
Just for information, when I uninstall com.google.android.webview, K-9 Mail stops working properly. The program launches and lists messages, but when I try to open a message, the program crashes. I tried installing org.bromite.webview as a substitute, but it didn't help. With com.google.android.webview present, K-9 Mail works flawlessly.

Android version: 6.0 (can't upgrade)
MIUI version: Global 10.2.1.0

The issue describes a crash in K-9 Mail when com.google.android.webview is uninstalled on a specific Xiaomi device. Research involves understanding Android WebView dependencies, the debloater's removal logic, and testing on similar Android 6.0 environments. Check the debloater's package list and removal scripts, then verify if K-9 Mail's message rendering relies on a specific WebView implementation.
