Noticed that the backdrop was removed and then re-drawn on each step of the tour.
These operations for removing and then creating new DOM elements are expensive and can be avoided as only a couple of styles are changed. We can only update the needed properties when needed.
Other benefit of reusing the same elements is the ability to incorporate animations on transition later.
I have implemented this optimization with this change.
