On Chrome, the element disappears once but loses focus and reappears
because the :focus style rule is no longer applicable after blur.
On Firefox 37.0.1(Linux)/Safari 8.0.5(OSX10.10)/IE11(Win8.1),
clicked element disappears and does not reappear.

It seems Chrome is conforming to the spec
but other browsers behave differently.
To make the behavior interoperable, fix the spec to match other browsers
and fix Blink, or wait for other browsers to catch up the spec.
