5.1.0 Throwing JSDisconnectedException after browser closed, left then reopened

[Richard McCavery]

Tried this with .net6.0 official release version and working very well generally however, if you display a SWAL dialog, then close your browser window with your web application still running and wait for approximately 2 minutes and try and use the same SWAL dialog a JSDisconnectedException is thrown when calling SWAl.FireAsync.

I am only using JS interop functionality in OnAfterRenderAsync as recommended by MS

Microsoft.JSInterop.JSDisconnectedException
HResult=0x80131500
Message=JavaScript interop calls cannot be issued at this time. This is because the circuit has disconnected and is being disposed.

Expected behavior
The IJSRuntime is injected without issue

Fails with multiple browsers.

Visual Studio 2022 net6.0 both released official versions
