Holding TAB key down across multiple controls crashes app

Issue

When holding down the TAB key to quickly change focus across multiple SfNumericEntry controls, the app will eventually crash.

The issue is intermittent and doesn't always present itself so it could be a race condition or threading issue.

Multiple attempts may be required to reproduce the issue.

(Side Note - I have also noticed that a "dotnet clean" is required to rebuild the project after the crash occurs in the debugger.)


Stack Trace

{System.NullReferenceException: Object reference not set to an instance of an object.

   at Syncfusion.Maui.Inputs.SfNumericEntry.OnTextBoxPreviewKeyDown(Object sender, KeyRoutedEventArgs e)
