Blazor client side Unable to find a default constructor to use for type System.IdentityModel.Tokens.Jwt.JwtPayload.

### Describe the bug
I'm using blazor client side and System.IdentityModel.Tokens.Jwt package v5.6.0.
When calling ReadJwtToken method on JwtSecurityTokenHandler I get the following exception

`Newtonsoft.Json.JsonSerializationException: Unable to find a default constructor to use for type System.IdentityModel.Tokens.Jwt.JwtPayload.`

I believe it has something to do with linker because if I add a redundant call to
`new System.IdentityModel.Tokens.Jwt.JwtPayload()`
in App.razor OnInitialized method it works.

I have tried adding

` `

to my Linker.xml file but that didn't help.
