Issue in private tab

[ScarletKuro]

I previously reported this issue in Discord, but to ensure it is not overlooked, I am now creating a formal issue here.

Steps to reproduce:

1. Open a private tab in Edge
2. Navigate to https://try.mudblazor.com/snippet
3. An exception will appear
4. Refresh the page and the error disappears
5. Close all instances of Edge and repeat step 1 to see the error reappear.

Exception:

crit: Microsoft.AspNetCore.Components.WebAssembly.Rendering.WebAssemblyRenderer[100]
      Unhandled exception rendering component: Cannot read properties of null (reading 'DarkTheme')
      TypeError: Cannot read properties of null (reading 'DarkTheme')
