Application icons don't follow the theme
Status in gnome-software package in Ubuntu:
Icons of applications within the store are fixed and don't follow the
theme chosen by the user. This makes the icons ugly and out of place
when using any icon theme different from the default.
Icons of common applications to follow the custom icon theme chosen by the
Icons are displayed according to the default theme (ubuntu-mono-*).
