It really will depend upon what is seen as the first strongly typed character in the first domain name. The Arabic/Hebrew/N’ko scripts all have an RTL script order within the RTL text direction for each language. Arabic and Hebrew both have characters commonly used (Unicode common) that the BiDi algorithm is required to treat as strongly typed LRT script order. Because of that, I doubt it’s enough to specify just the text direction for each element.

work through both to make it work.
