GUI doesn't open (only in tray) until Big Picture Mode has been activated and exited.

It's somewhat self-explanatory - the GUI doesn't open most of the time. However, interestingly, a comment downstream (flathub/com.valvesoftware.Steam#1306 (comment)) has ascertained a workaround:

What I figured out is, when that happens, you can click on the tray icon and select big picture mode (which mostly would work, but there are times even that would not do anything)....and then exit out of big picture mode and it should take you to the normal window.

Steps for reproducing this issue

Log in after installation. It doesn't appear to occur until the account has been authenticated. After that, it occurs frequently, but inconsistently.

@kisak-valve, do note that it applies to both the sandboxed .flatpak and unsandboxed .RPM, if that wasn't evident. Thanks for the triage.
