Hello John,

This is my extension:
   https://github.com/SauceLLC/sauce4strava
   https://apps.apple.com/us/app/sauce-for-strava/id1570922521
   https://addons.mozilla.org/en-US/firefox/addon/sauce4strava/
   https://chrome.google.com/webstore/detail/eigiefcapdcdmncdghkeahgfmnobigha

And you are correct, I already released patched builds (v8.2.2) on the Apple and Firefox stores.

This is the commit with my workaround: https://github.com/SauceLLC/sauce4strava/commit/9100e2db6245b5db7bf104b3044029d0b936ec7a

I don't know how to get you a Safari based build with the old behavior from the app-store, but if you use Onion you can install this unpatched firefox build: https://addons.mozilla.org/firefox/downloads/file/4078653/sauce4strava-8.2.1.xpi

I should warn you that you'll probably need to create an account with strava.com first.  It's free, but there would be some tedium in trying to repro from my particular extension.  You'll also need to be on a page that invokes these postMessage calls, such as this example: https://www.strava.com/activities/8355858982
