In a perfect world I would have wanted the translation engine to swap the website UI itself to RTL along with the text being translated, but alas, I think this is almost impossible to cater for every possible scenario, and there are many.
Since that's out of the question, when changing the direction of the element you also align it to the right, and this would not look food on all websites or UI layouts.
So additionally, I think something like `text-align: match-parent` would also be needed, to let the text (in the LTR->RTL case) be aligned to the left still, even though that's not "correct" for RTL users (or LTR users, for the RTL-LTR case). Having text being readable is more important than having it aligned to the correct side, I think.
Of course, this isn't a perfect solution for all cases, since I can assume there would be contexts where the parent's text alignment is not the same as the child, but I'm guessing this is a minor enough issue to let it slide.
