Can not select a different session only with keyboard

[megatux]

Tried to change from Pantheon to other session type (i3, XFCE, etc) only with keyboard. I can display the list of sessions but tried with SPACE and ENTER keys and the hovered one is selected. (ENTER key closes the list but don't change selection and with SPACE key, it is added to the password input string)

It looks like you can focus and activate the radiobutton with the keyboard, but activating the modelbutton doesn't automatically activate the radiobutton

Hi, it's been a while since I reported this issue. I'm not a Vala programmer but maybe I could take a look at the code. What should be the right keys behaviour, based on a normal GTK keyboard navigation? SPACE should select the item in the list? ENTER should start the session with the selected DE? Thx
