(I'm not going to bug theymos with a PM about this one, so, hopefully he bumps into this post naturally. I didn't test this change very carefully, because that's always the most time-consuming part of the process, and it doesn't make much sense for me to allocate a huge block of time to doing cross-browser testing for a proposed change that theymos might never even see, let alone merge. If he merges it and it turns out that I've overlooked something, like maybe selection-preservation not working exactly how it used to, then the change can be undone and I'll attempt to revise/improve it at that point.)
Thanks for the work @PowerGlove. Since there is no newer forum software development to worry about, I believe it's not a bad idea to improve on what we have right now.
Let's wait and see if admin can pick up interest regarding this and add some changes, or perhaps he will be reluctant due to the recent merit source mess? Time will tell.
