    Galaxy features many different transition effects that change the page state over time.
    These transitions make it slightly more difficult to test Galaxy because atomic input
    actions take an indeterminate amount of time to be reflected on the screen. This method
    takes a Selenium assertion and tries to infer if such a transition could be the root
    cause of the exception. The methods that follow use it to allow retrying actions during
    transitions.

    Currently the two kinds of exceptions that we say may indicate a transition are
    StaleElement exceptions (a DOM element grabbed at one step is no longer available)
    and "not clickable" exceptions (so perhaps a popup modal is blocking a click).
