When event is triggered twice one step is skipped

[mikocot]

In some particular cases an event can be propagated and immediately triggered again.

This situation happens for example inside a checkbox generated by semantic-ui.
In that case a click on a checkbox label is wired to immediately perform a click on the checkbox input.

This is a convenient mechanism for user, but ends up with 2 simultaneous clicks performed within an element wrapping the whole control.
