Polly handles a few exceptions like expected first but then System.Private.CoreLib.dll steps in and triggers an unhandled exception

The program below behaves as expected for three retries but then crashes:

$ ./PollyTest/bin/Debug/net8.0/PollyTest.exeHello, World!retry number 0retry number 1retry number 2Unhandled exception. System.ApplicationException: work work   at Program.<<Main>$>g__WorkAsync|0_1(CancellationToken token) in C:\git\test\pollytest\PollyTest\PollyTest\Program.cs:line 34   at Program.<>c.<<<Main>$>b__0_0>d.MoveNext() in C:\git\test\pollytest\PollyTest\PollyTest\Program.cs:line 25--- End of stack trace from previous location ---   at Polly.ResiliencePipeline.<>c.<<ExecuteAsync>b__3_0>d.MoveNext()--- End of stack trace from previous location ---   at Polly.Outcome`1.GetResultOrRethrow()   at Polly.ResiliencePipeline.ExecuteAsync(Func`2 callback, CancellationToken cancellationToken)   at Program.<Main>$(String[] args) in C:\git\test\pollytest\PollyTest\PollyTest\Program.cs:line 23   at Program.<Main>(String[] args)$

with the following source code:

using Polly.Retry;using Polly;// See https://aka.ms/new-console-template for more informationConsole.WriteLine("Hello, World!");var retryOptions = new RetryStrategyOptions{    BackoffType = DelayBackoffType.Exponential,    Delay = TimeSpan.FromMilliseconds(100),    MaxDelay = TimeSpan.FromSeconds(60),    OnRetry = arguments =>    {        Console.WriteLine($"retry number {arguments.AttemptNumber}");        return default;    },    ShouldHandle = args => PredicateResult.True(),};var pipeline = new ResiliencePipelineBuilder()    .AddRetry(retryOptions)    .Build();await pipeline.ExecuteAsync(async token =>{    await WorkAsync(token);}, CancellationToken.None);return;///////////////////////////////////static Task WorkAsync(CancellationToken token){    throw new ApplicationException("work work");}

When running in debug mode in Visual Studio, the following is printed in the Debug output

...'PollyTest.exe' (CoreCLR: clrhost): Loaded 'C:\Program Files\dotnet\shared\Microsoft.NETCore.App\8.0.2\System.ObjectModel.dll'. Skipped loading symbols.

so obviously all Exception thrown: ... in PollyTest.dll are captured and handled as expected but Exception thrown: ... in System.Private.CoreLib.dll is not. But why is suddenly System.Private.CoreLib.dll involved? How can I avoid?

This is with Polly version 8.3.0.
