Describe the bug

Application displays the error message at the bottom of a default application. Error occurs because the CSS uses media queries with deprecated features: '-ms-high-contrast'. See https://blogs.windows.com/msedgedev/2024/04/29/deprecating-ms-high-contrast/ for more information.

To Reproduce
Steps to reproduce the behavior:

  1. Setup a new Blazor Maui Hybrid app
  2. Follow the instructions to setup a Webassembly standalone application.
  3. Use the "standard-dark.css" file.
  4. See error at the bottom of the screen.

Expected behavior
Expected no error message to be displayed since there were only warnings.
