Microsoft.FluentUI rendering problem on refresh

Have a rendering problem when using FluentUI.The problem is - when you refresh the page (F5) - it is blinking (looks like initially it's rendered without any styles and only after few milliseconds the styles are applied)

It's easily can be reproduced with using FluentUI template

dotnet new install Microsoft.FluentUI.AspNetCore.Templatesdotnet new fluentblazor --name MyFluentAppcd MyFluentAppdotnet run

Especially, this is easy to see on /weather page

Is it possible to eliminate those blinkings?
