#
# This is based on getBoundingClientRect, where Y is the distance
# from the top of the element to the top of the viewport, and X
# is the distance from the leftmost edge of the element to the
# left of the viewport. The viewpoint origin (0, 0) is at the
# top left of the page.
#
# Once X and Y stop changing based on the current vs previous position,
# then we know the animation has stopped and the element is stabilised,
# at which point we can click on it without fear of Capybara mis-clicking.
