Aspnetcore: Safari 13.0 and Blazor incompatibility

[larsbj]

Describe the bug

Using Safari Version 13.0 (14608.1.49) on Mac OS X 10.14.6 I'm unable to get any Blazor demo working.

To Reproduce

Go to (random example) https://blazorwithidentity.azurewebsites.net
The page is stuck at "Loading..."

The Javascript Console shows:

Unhandled Promise Rejection: TypeError: 'arguments', 'callee', and 'caller' cannot be accessed in this context. https://blazorwithidentity.azurewebsites.net/_framework/wasm/mono.js 208786

This also applies to creating a new dotnet blazor locally.

Expected behavior

I expected the page to load.

I believe this is a known issue in safari with the current version of mono we are using. @SteveSandersonMS can confirm.

Thanks for contacting us, @larsbj.
This is a bug in the underlying Mono framework, which we hope will be fixed in the upcoming release.

@mkArtakMSFT I'm getting the same error on Safari Version 13.0.1 (14608.2.11.1.11) with Mac OS Version 10.14.6 (18G95)

Do you have any idea when the next release with a fix will be out?

Was this resolved at all? I'm experiencing the same issue
