When I have HTML element which has 2 event handlers attached which should file due to the same event on the element e.g. onMouseUp and onClick. I have suspicion that I might have race conditions in code related with order of these events.

Is there some specific order ( described by spec / prescribed by code implementation ) these event handlers?

P.S. I can obviously create small Codepen and do empirical tests, but want to know in what way these things are implemented and if something governs the order they are executed in.
