Notifications don't seem to work in PWAs
After creating a PWA, I notice that sites capable of notifications are not able to successfully send them via the PWA itself. Angelfish handles notifications appropriately if the app is used in the browser, rather than a PWA. So, this seems to be an issue specific to PWAs themselves.
The Angelfish PWA will ask for notification permission each time the app attempts to send them, but clicking "Accept" seems to have no effect, unlike within the normal browser window.
So far, I have found that Angelfish's PWAs have allowed me to avoid using Waydroid to support business-critical nonfree applications, which is massively helpful in my migration from Android!
I am using stable-branch Manjaro ARM w/ Plasma Mobile (beta 10) on Pinephone Pro.
