gnome-software does not exit a search

[C de-Avillez]

I (accidentally) started Rhythmbox for the firt time ever at this laptop. It started, and a pop-up came asking if I wanted to install additional needed codecs (title line says "Available software for MPEG-4 ACC decoder", so I guess this was the search argument.

I accepted, and gnome-software opened with a search result for GSTreamer codecs. I installed two of them, life is good, closed (Alt-F4) gnome-software.

Then I decided to install some other package via GS as well. Opened (again) it, and... I am shown a search result for GStreamer codecs. I cannot exit this search. (via the "<" at the left of the title line). I can only close the thing.

End result: gnome-software is now, for all practical purposes, unavailable. Hence, the bug.
