Cannot control updates tab from keyboard
I've just upgrade an old machine from Gnome 3.24 to Gnome 3.28 (Fedora 26 -> 28). That machine lacks a mouse/trackpad (laptop, driver issues).
Previously I could navigate the tab bar using ctrl-tab + cursors keys in order to trigger the update.
I can still select the tabs at the top and swap to the Updates tab. BUT once there I cannot reselect the tabs and cannot trigger the 'check for updates' button in the top left.
Previously this was possible with the combination of tab/ctrl-tab/cursors.
Thanks for a great piece of software and its nice accessibility works so well normally
