PAR (pushed authorization requests) are not retried

The connection between our site and our IdP is sometimes experiencing minor connection difficulties. It looks like pushed authorization requests (introduced by our switch from .NET 8 to .NET 10) from our Application to the IdP sometimes fail and are not retried at all. This problems (=HttpRequestExceptions) are bubbled up and ultimately trigger a 500 error during authentication.

Is there a reason why options.Backchannel from the OpenIdConnectOptions is a HttpClient without any resilience pipeline in place? If not, I can simply set the Backchannel property to an HttpClient instance with one in place and thereby resolve these connection problems, right?

Best regards,
