The relevant commit is https://gitlab.gnome.org/GNOME/gnome- software/commit/ca5f8e74b6f9991ae228caa2c698131a54764774, and I verified that applying it as a patch on top of gnome-software 3.30.2-0ubuntu7 fixes the issue. In fact, with this change, when re-opening gnome- software after closing it while seeing the details of an app, the application is reset to the main screen. Which may or may not be seen as desirable, but at least it fixes the bug.
