* Adds a unit test to stop elements from using identical lists for their arguments. (#76322) ## About The Pull Request Ok, so a few days ago I made an issue report about multiple instances of identical elements being generated because of uncached lists. ninjanomnom (the mind being the element datums) cleared it up and said an implementation of GetIdFromArguments() that also checks the list contents wouldn't be worth the performance cost, while adding that a unit test should be written to check that it doesn't happen at least during init, which should catch a good chunk of cases. Also, i'm stopping RemoveElement() from initializing new elements whenever a cached element is not found. Ideally, there should be a focus only unit test for that too, but that's something we should tackle on a different PR. Some of the code comments may be a tad inaccurate, as much as I'd like to blame drowsiness for it. Regardless, the unit test takes less than 0.2 seconds to complete on my potato so it's fairly lite. ## Why It's Good For The Game This will close #76279. ## Changelog No player-facing change to be logged. * Adds a unit test to stop elements from using identical lists for their arguments. * Fixes unit test * seeing double --------- Co-authored-by: Ghom <42542238+Ghommie@users.noreply.github.com> Co-authored-by: Giz <13398309+vinylspiders@users.noreply.github.com>
