Currently, the schema text looks broken if the user language is right-to-left:

We need to make sure the schema text always goes left-to-right. This can be done by setting dir="ltr" on the element or by wrapping it inside a [<bdi> element](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/bdi).

We also need to think about what to do with the edit links. Due to automatic flipping, they currently float to the left in RTL languages, but if the schema text goes left-to-right then they’ll collide (the first lines of the schema text will move out of the way to accommodate the floating section). We can instruct CSSJanus not to flip them, but then what should happen to the order of the links? Should they still be swapped even if the link group floats in the same place in languages of either direction?
