Currently we show the workspace popup for relative targets ("up", "down"),
but not when targetting a specific workspace directly.
There is not really a good reason for that difference, and as we are about
to introduce a new shortcut to target the last workspace (which does vary
with dynamic workspaces), it makes sense to unify the behavior and always
show the switcher.
