[Entry] [Android] Cursor makes undesired jumps with Masked Behavior

[Hackmodford]

Description

Using the .NET MAUI Entry control works fine in both android and iOS, but applying behaviours such as MaskedBehvior from .NET MAUI Community Toolkit (or others) ends up un randomic cursor movements on Android, iOS doesn't present this strange behaviour.

Steps to Reproduce

1. Create a MAUI App.
2. Download package CommunityToolkit.Maui and follow instructions to make it work.
3. On Main page put a entry with behaviour:

<Entry>
   <Entry.Behaviors>
      <mtc:MaskedBehavior Mask="XXXX XXXX XXXX XXXX" />
   </Entry.Behaviors>
</Entry>

4. Start writing and see randomic cursor dance.
