Steps to reproduce

I have a simplified page below to try. If you load this you will see an error in the console "CSS3120", the error is because it cannot load the helvetica bold font on windows.

I have 2 questions

  1. Since I have Segoe UI in the font-family list before helvetica I don’t know why edge even tried to load the helvetica as it won’t be used. Possibly it’s fetching the file before parsing for perf reasons?

2)If it’s not possible to avoid fetching unused fonts, can you downgrade this to a warning? There is a font-family list for a reason, if you can’t get the first one it falls back, so it’s not necessarily an error, in my case it’s expected behavior.

html {
  font-family: "Segoe UI", "Helvetica Neue", Arial, sans-serif;

/*on windows load segoe bold*/
font-face {
  font-family: "Segoe UI";
  font-weight: 800;
  src: local("Segoe UI Bold"); }

/*on mac load helvetica bold*/
font-face {
  font-family: "Helvetica Neue";
  font-weight: 800;
  src: local("Helvetica-Bold"); }
  <div>hello world</div>
  <div style="font-weight: 800;">hello world font-weight 800</div>
