Comment 2 for bug 1963861

@alexmurray that code has never listed or show which application would handle given URL scheme. The change affected the implementation of io.snapcraft.Launcher, which is only called as a fallback when a snap calls xdg-open inside it's namespace. The primary handler that is tried goes through the desktop portal https://flatpak.github.io/xdg-desktop-portal/#gdbus-org.freedesktop.portal.OpenURI which AFAIU prompts to select an application for some number of attempts, which then goes away if the user chose consistently chose the same application each time. So if the prompt was originally shows, but now it's not, my guess would be that it's the portal.

The fallback code would open an application for which there is a desktop handler registered in the mime db. Perhaps we could improve that to show a prompt? Anyways, this code isn't part of any stable release yet.
