There used to be a problem with the setfont and setrtl script commands. Namely, if you used them in between text boxes naïvely, without any careful thought, then the fading out text box would suddenly gain the font of the new one. A kludge solution to this was implemented by simply blocking the script until the existing text box faded out before switching the font or RTL, and shipped for 2.4.0. However, a better solution is to simply bake the font flags in to the text box, so that way, if the level font switches, then the text box keeps its font. This is only for custom levels, because in the main game, the font in a text box needs to be able to change depending on language. But it seems like custom level translations weren't much on the roadmap, and so even the existing hack didn't support changing the font based on translation (even though translation of custom level cutscenes is supported). So baking the font flags into the text box here doesn't make things any worse. It also makes things better, arguably, by allowing multiple text boxes to exist on screen at once with different fonts. Maybe in the future we'll need a flag that specifies that the font should change depending on language if a translation in said language exists for the text box, or something like that. For people that want to override the fonts of every existing text box on screen, you can specify "all" as the second parameter of setfont or setrtl to do so.
