[Kaiffa]

Description

Trying to set the underline to transperent but it's not working in NET 8, but it did work on NET 7 and before.
Also true for other handlers (picker, editor etc.)
Tried on android (but possibly the same on iOS)

NET 8:

Steps to Reproduce

1. Create new MAUI .NET8 project
2. Add Entry to MainPage
3. Add Custom handler code in MauiProgram:
