What's not working

"Pending" category does not show the pending packages after selecting a new package to install on pamac-gtk (4), while working on pamac-gtk3

How to reproduce?

• Open pamac-gtk (4), click on the blue arrow to select a new package to install
• The footer of the window changes to "1 pending operation", Pending appears as category in the left sidebar, but clicking on it does nothing (on pamac-gtk3 it shows a list of the packages selected for install and thus pending)
