Allow Spatial Navigation with continual arrow press
If I press the down arrow, the page scrolls down one unit of scrolling.
If I keep the down arrow pressed continually, the page scrolls continually until I let go.
If I am using spatial navigation, and I do Shift+Down, Vivaldi moves the selection down once.
If I keep Shift+Down pressed, nothing happens.
I would expect Vivaldi to quickly cycle down through the links until I let go of Shift+Down.
I appreciate that spatial navigation is an accessibility enabler, so this might need to be an optional setting.
