Fix popover not popping up

Sometimes the "focus-marker" gets clicked. In this situation,
it will trigger an open, and then a close, because the original
focus-marker was removed from the dom, so $el.contains() no
longer thinks the marker is part of the trigger! We replaced the
v-if with v-show to resolve this problem.
