Actually the problem is the toggling of 'display' on the 'a' element.

So I have a fix for this part of this, however it 'breaks' your
example.
Because you 'undisplay' the 'a' element in the 'capture' phase before the
click get's to the 'a' element. The fix unregisters the click listener
when
the element becomes undisplayed. I may look at other ways to manage this
in
the future as this 'feels' a little odd, but I doubt there is anything to
say
that this is truly wrong - doing things during capture is likely to lead
to
'strangeness'.
There are two main work around for this:
1) move your undisplay code to the 'bubble' phase.
2) switch to toggling visibility rather than display.
