Gnome Software window when BricsCAD RPM is opened in it.

Description of problem:

When I try to install BricsCAD RPM package via Gnome Software, it's long description makes the Gnome Software window very large (see attachement).

Version-Release number of selected component (if applicable):
gnome-software.x86_64                 3.18.3-1.fc23


How reproducible:
Always.

Steps to Reproduce:

2. Navigate to the directory where RPM was downloaded.

The window becomes very large because package description read from the RPM isn't wraped.
