// no-badge-preload.js — session-wide preload (frames and service workers)
|
||
|
|
// that removes the web Badging API before any site code runs.
|
||
|
|
//
|
||
|
|
// navigator.setAppBadge(n) makes Electron draw n over the app's taskbar icon.
|
||
|
|
// Every site wrote that same single number, so the icon said "40" with no way
|
||
|
|
// to tell whose 40, and Theseus shows no unread counts on its icon at all.
|
||
|
|
// Deleting the methods (rather than making them do nothing) lets a site see a
|
||
|
|
// browser without badges and fall back to its own title or favicon counter.
|
||
|
|
// The Chromium switch --disable-blink-features=Badging no longer removes the
|
||
|
|
// API, which is why this runs as a preload. Electron runs no preload in an
|
||
|
|
// about:blank or srcdoc iframe, so a page could still reach the API through
|
||
|
|
// one; sites set their counts from the page or its service worker, which is
|
||
|
|
// what this covers.
