When using zone.js with dojo, dropdown widgets (datepicker, combobox, etc) don't register click events when interacted with.

Simple reproduction steps: https://github.com/mcgraphix/zonejs-dojo-bug

That repo is currently using 0.8.26. If you revert to 0.8.12 in the script tag, the widget will start working.
