Installing an app, progress bar is stuck on 0% for 5+ minutes
I was just installing an app from Flathub and the progress bar was stuck on 0% for quite a long time - at least 5 minutes. This might have been because a runtime was being downloaded. We should obviously show some feedback during this time - otherwise it looks like it has broken.
Having the progress bar throb with a "Downloading..." label might be the simplest solution.
