The network and wifi plasmoid is not keyboard navigate able
Reproduce:
Click on network and wifi icon in panel
arrow up/ down or press tab
result:
the list entries (devices) are never focused
only the embedded "connecting" / "disconnecting" button is not focus able
What should happen:
the list entries (connections) should be focus able using arrow up/down
pressing tab should focus the connection / disconnection button for the selected list entry
pressing up /down should move in the list up or down
i mark it as high since the system settings doesn't work here as well (broken keyboard navigation). Without a blind person don't have access to an network without fiddling with nmctl or similar
