[Android] Effect disappearing when changing tabs on Shell TabBar

[RandomMauiDev]

Description

I have a simple effect for Entry view called NoBackgroundEffect which on Android removes underline:

editText.SetBackgroundColor(Android.Graphics.Color.Transparent);

App is using AppShell + TabBar with two tabs. Inside one tab there is a button that opens up a new page in the tab. That page contains Entry with effect. When you swap tabs and go back to the page with Entry - effect is no longer there. You can see underline on the entry.

Steps to Reproduce

1. Create effect for Entry
2. Create AppShell with 2 or more tabs in TabBar
3. Create a button to open a new page inside a tab
4. Add Entry with effect to that page
5. Swap tabs and see the effect disappear from the Entry
