<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Bootstrap/Load: Add `HTTP/3` as a valid HTTP protocol.
As of November 2021, the `HTTP/3` protocol is still officially an Internet Draft, but is already supported by 74% of running web browsers and, according to W3Techs, 23% of the top 10 million websites. It has been supported by Google Chrome (including Chrome for Android, and Microsoft Edge, which is based on it) since April 2020 and by Mozilla Firefox since May 2021. Safari 14 (on macOS Big Sur and iOS 14) has also implemented the protocol but support is hidden behind a feature flag.
Based on the wide support, this change adds `HTTP/3` as a valid HTTP protocol.
Props malthert.
