As you may see in the following test: https://www.webpagetest.org/result/190227_7Q_6d5605d1a6a34d93fcc1497a3cebeb35/1/details/#waterfall_view_step1, the request for .woff2 font files failed with 404 in the first try. Whereas, the later retry succeeded.
However, the waterfall for the same page when browsing in browser (like Chrome) showed no 404 errors for the .woff2 font files.
Can anyone shed some light on this behavior? Is it particular to WPT?
