All solutions are bad – when not coming from the WPENGINE team.
But still, this is a good one. I have said to my clients that “click preview a second time if you do not see the preview correctly”.
But your solution – it should also only be needed if the post has zero revisions I guess? Which you could check for, and then add this extra step.
I like the “frontend” approach to this, instead of the more hacky php ways with actions/hooks.
