    The normal behavior of cards is to wait a quarter of a second before displaying on mouseover, so the mouse can
    move across the UI without flashing a bunch of pets the user isn't interested in. The same principle is being
    applied to tooltips (including ability tooltips and other tooltips).

    Since tooltips are never interactable, so they don't lock or pin, the behavior is essentially just delaying to
    show and that's it.  So adding this behavior is simply starting a timer to show the tooltip and stopping the
    timer if the tooltip is being hidden.

    The function rematch.tooltipManager:AddBehavior(tooltip) will add this behavior to any frame given as a tooltip,
    though it should only be used for frames that are mouse disabled.

    Then any tooltip:Show() will wait a quarter of a second (or whatever the TooltipBehavior setting says) before
    showing the tooltip.

    It's up to the calling function to handle all anchoring and updating the contents of the tooltip.
