Search results in GNOME Shell Overview do not include Fedora third-party repositories
When opening a GNOME Shell Overview mode (using Super/Windows key) and searching for "Steam", "NVIDIA" and other things that are available in the official Fedora third-party repositories, no results are found on a Fedora 32 system with third-party repositories enabled (and no regular RPM Fusion or Flathub repositories enabled). They are found only after opening the "Software repositories" window in GNOME Software and enabling the individual sources - for example, "Steam" can be found only after manually enabling the "RPM Fusion for Fedora 32 - Nonfree - Steam" source and killing gnome-software.
This happens on fully updated Fedora 32 with gnome-software-3.36.0-2.fc32.x86_64.
I have tried this on multiple user accounts and it happened every time so it is definitely a bug, not a cache issue.
When opening GNOME Software and searching for "Steam" or "NVIDIA", all results are found without any issue. The issue happens only for results displayed in GNOME Shell Overview.
